Facebook Connection Failed to GameSparks Server in Unity - facebook

I'm setting up the Facebook Connection to GameSparks server with FacebookConnectRequest using Facebook SDK for Unity. However, I'm getting an error response with key "accessToken" and value "NOTAUTHENTICATED". The details of the error is "The system was unable to authenticate the token.".
I have tried to reimport Facebook and GameSparks SDK in Unity. Change the some initialization of the Facebook and GameSpark in the code. However, I could not come up with a solution.
public void ConnectPlayerViaFacebook()
{
ChangeCurrentText("Connecting Facebook With Server...");
Debug.Log("Connecting Facebook With GameSparks...");// first check if FB is ready, and then login //
// if it's not ready we just init FB and use the login method as the callback for the init method //
if (!FB.IsInitialized)
{
ChangeCurrentText("Initializing Facebook...");
Debug.Log("Initializing Facebook...");
FB.Init(ConnectGameSparksToGameSparks, null);
}
else
{
FB.ActivateApp();
ConnectGameSparksToGameSparks();
}
}
///<summary>
///This method is used as the delegate for FB initialization. It logs in FB
/// </summary>
private void ConnectGameSparksToGameSparks()
{
if (FB.IsInitialized)
{
FB.ActivateApp();
Debug.Log("Logging into Facebook...");
ChangeCurrentText("Logging into Facebook...");
var perms = new List<string>() { "public_profile", "email" };
FB.LogInWithReadPermissions(perms, (result) =>
{
if (FB.IsLoggedIn)
{
ChangeCurrentText("Logged in, Connecting Server via Facebook...");
new FacebookConnectRequest()
.SetAccessToken(AccessToken.CurrentAccessToken.TokenString)
.SetDoNotCreateNewPlayer(false)
.SetDoNotLinkToCurrentPlayer(false)
.SetSwitchIfPossible(false)
.SetSyncDisplayName(true)
.Send((fbauth_response) =>
{
if (!fbauth_response.HasErrors)
{
...
}
else
{
Debug.Log(fbauth_response.Errors.JSON.ToString());
ChangeCurrentText("Server Authentication with Facebook Failed!" + fbauth_response.Errors.JSON.ToString());
}
});
}
else
{
Debug.LogWarning("Facebook Login Failed!" + result.Error.ToString());
ChangeCurrentText("Facebook Login Failed!" + result.Error.ToString());
}
});
}
else
{
ConnectPlayerViaFacebook(); // If we are still not connected, then try to process again
}
}
I want to remove the error response of the FacebookConnectRequest of the GameSparks request.

Thanks to derHugo's advice I have solved the problem. For some reasons the acces token is broken before the FacebookConnectionRequest. To prevent any undesirable situation about access token it needs to be manually refreshed. To do it, FB.Mobile.RefreshCurrentAccessToken needs to be used before FacebookConnectionRequest.
The explanation of that function is as follows: It may be desireable to manually refresh the current access token granted to the application by the user in order to retrieve up-to-date permissions, and extend the expiration date, if extension is possible. Use FB.Mobile.RefreshCurrentAccessToken to accomplish this. (source)
if (FB.IsLoggedIn)
{
FB.Mobile.RefreshCurrentAccessToken(callback =>
{
...
});
ChangeCurrentText("Logged in, Connecting Server via Facebook...");
new FacebookConnectRequest()
.SetAccessToken(AccessToken.CurrentAccessToken.TokenString)
.SetDoNotCreateNewPlayer(false)
.SetDoNotLinkToCurrentPlayer(false)
.SetSwitchIfPossible(false)
.SetSyncDisplayName(true)
.Send((fbauth_response) =>
{
...
});
}
else
{

how do I redirect to my own custom logout page after the logout process has completed with .net core 5

Whenever I logout from my app Im taken to a 'default' logged out page (I believe this controller action is built in to .net core). How do I perform a logout redirect to a custom page within my app after Ive been logged out ? I cant see a way to specifiy this, surely it must be possible ? (it was in older versions of .net).
Im using azure ad and my app is hosted in azure. This is the configuration
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.Unspecified;
// Handling SameSite cookie according to https://learn.microsoft.com/en-us/aspnet/core/security/samesite?view=aspnetcore-3.1
options.HandleSameSiteCookieCompatibility();
});
// Sign-in users with the Microsoft identity platform
services.AddMicrosoftIdentityWebAppAuthentication(Configuration, "AzureAd");
I also have these settings in appsettings.json
"CallbackPath": "/signin-oidc",
"SignedOutCallbackPath ": "/signout-callback-oidc"
Ive also tried this
new RewriteOptions().Add(
context => {
if (context.HttpContext.Request.Path == "/AzureAD/Account/SignedOut")
{ context.HttpContext.Response.Redirect("/Home/Index"); }
})
);
and even tried adding my own AccountController with these 2 methods
[HttpGet]
public override SignOutResult SignOut()
{
var callbackUrl = Url.Action(nameof(SignedOut), "Account", values: null, protocol: Request.Scheme);
return SignOut(
new AuthenticationProperties { RedirectUri = callbackUrl },
CookieAuthenticationDefaults.AuthenticationScheme,
OpenIdConnectDefaults.AuthenticationScheme);
}
[HttpGet]
public IActionResult SignedOut()
{
if (User.Identity.IsAuthenticated)
{
// Redirect to home page if the user is authenticated.
return RedirectToAction(nameof(HomeController.Index), "Home");
}
return RedirectToAction(nameof(HomeController.Index), "Home");
}
Nothing works, Im always redirected to the 'default' logged out page. Can anyone help ? thanks in advance
I managed to solve this, I changd my Rewite code to this
app.UseRewriter(
new RewriteOptions().Add(
context => {
if (context.HttpContext.Request.Path == "/MicrosoftIdentity/Account/SignedOut")
{ context.HttpContext.Response.Redirect("/Home/SignedOut"); }
})
);
this was the part I had to modify
from
"/AzureAD/Account/SignedOut"
to
"/MicrosoftIdentity/Account/SignedOut"
now it works

Why may I be getting empty data field from facebook? [duplicate]

I am trying to get my friend name and ids with Graph API v2.0, but data returns empty:
{
"data": [
]
}
When I was using v1.0, everything was OK with the following request:
FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error) {
NSArray* friends = [result objectForKey:#"data"];
NSLog(#"Found: %i friends", friends.count);
for (NSDictionary<FBGraphUser>* friend in friends) {
NSLog(#"I have a friend named %# with id %#", friend.name, friend.id);
}
}];
But now I cannot get friends!
In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.
In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.
If you want to access a list of non-app-using friends, there are two options:
If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.
If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.
In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission). This has been confirmed by Facebook as 'by design'.
For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.
UPDATE: Facebook have published an FAQ on these changes here: https://developers.facebook.com/docs/apps/faq which explain all the options available to developers in order to invite friends etc.
Although Simon Cross's answer is accepted and correct, I thought I would beef it up a bit with an example (Android) of what needs to be done. I'll keep it as general as I can and focus on just the question. Personally I wound up storing things in a database so the loading was smooth, but that requires a CursorAdapter and ContentProvider which is a bit out of scope here.
I came here myself and then thought, now what?!
The Issue
Just like user3594351, I was noticing the friend data was blank. I found this out by using the FriendPickerFragment. What worked three months ago, no longer works. Even Facebook's examples broke. So my issue was 'How Do I create FriendPickerFragment by hand?
What Did Not Work
Option #1 from Simon Cross was not strong enough to invite friends to the app. Simon Cross also recommended the Requests Dialog, but that would only allow five requests at a time. The requests dialog also showed the same friends during any given Facebook logged in session. Not useful.
What Worked (Summary)
Option #2 with some hard work. You must make sure you fulfill Facebook's new rules: 1.) You're a game 2.) You have a Canvas app (Web Presence) 3.) Your app is registered with Facebook. It is all done on the Facebook developer website under Settings.
To emulate the friend picker by hand inside my app I did the following:
Create a tab activity that shows two fragments. Each fragment shows a list. One fragment for available friend (/me/friends) and another for invitable friends (/me/invitable_friends). Use the same fragment code to render both tabs.
Create an AsyncTask that will get the friend data from Facebook. Once that data is loaded, toss it to the adapter which will render the values to the screen.

Facebook has revised their policies now. You can’t get the whole friendlist anyway if your app does not have a Canvas implementation and if your app is not a game. Of course there’s also taggable_friends, but that one is for tagging only.
You will be able to pull the list of friends who have authorised the app only.
The apps that are using Graph API 1.0 will be working till April 30th, 2015 and after that it will be deprecated.
See the following to get more details on this:
User Friends
Facebook Application Development FAQ
In Swift 4.2 and Xcode 10.1:
If you want to get the friends list from Facebook, you need to submit your app for review in Facebook. See some of the Login Permissions:
Login Permissions
Here are the two steps:
1) First your app status is must be in Live
2) Get required permissions form Facebook.
1) Enable our app status live:
Go to the apps page and select your app
https://developers.facebook.com/apps/
Select status in the top right in Dashboard.
Submit privacy policy URL
Select category
Now our app is in Live status.
One step is completed.
2) Submit our app for review:
First send required requests.
Example: user_friends, user_videos, user_posts, etc.
Second, go to the Current Request page
Example: user_events
Submit all details
Like this submit for all requests (user_friends , user_events, user_videos, user_posts, etc.).
Finally submit your app for review.
If your review is accepted from Facebook's side, you are now eligible to read contacts, etc.
As Simon mentioned, this is not possible in the new Facebook API. Pure technically speaking you can do it via browser automation.
this is against Facebook policy, so depending on the country where you live, this may not be legal
you'll have to use your credentials / ask user for credentials and possibly store them (storing passwords even symmetrically encrypted is not a good idea)
when Facebook changes their API, you'll have to update the browser automation code as well (if you can't force updates of your application, you should put browser automation piece out as a webservice)
this is bypassing the OAuth concept
on the other hand, my feeling is that I'm owning my data including the list of my friends and Facebook shouldn't restrict me from accessing those via the API
Sample implementation using WatiN:
class FacebookUser
{
public string Name { get; set; }
public long Id { get; set; }
}
public IList<FacebookUser> GetFacebookFriends(string email, string password, int? maxTimeoutInMilliseconds)
{
var users = new List<FacebookUser>();
Settings.Instance.MakeNewIeInstanceVisible = false;
using (var browser = new IE("https://www.facebook.com"))
{
try
{
browser.TextField(Find.ByName("email")).Value = email;
browser.TextField(Find.ByName("pass")).Value = password;
browser.Form(Find.ById("login_form")).Submit();
browser.WaitForComplete();
}
catch (ElementNotFoundException)
{
// We're already logged in
}
browser.GoTo("https://www.facebook.com/friends");
var watch = new Stopwatch();
watch.Start();
Link previousLastLink = null;
while (maxTimeoutInMilliseconds.HasValue && watch.Elapsed.TotalMilliseconds < maxTimeoutInMilliseconds.Value)
{
var lastLink = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& l.Text != null
).LastOrDefault();
if (lastLink == null || previousLastLink == lastLink)
{
break;
}
var ieElement = lastLink.NativeElement as IEElement;
if (ieElement != null)
{
var htmlElement = ieElement.AsHtmlElement;
htmlElement.scrollIntoView();
browser.WaitForComplete();
}
previousLastLink = lastLink;
}
var links = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& l.Text != null
).ToList();
var idRegex = new Regex("id=(?<id>([0-9]+))");
foreach (var link in links)
{
string hovercard = link.GetAttributeValue("data-hovercard");
var match = idRegex.Match(hovercard);
long id = 0;
if (match.Success)
{
id = long.Parse(match.Groups["id"].Value);
}
users.Add(new FacebookUser
{
Name = link.Text,
Id = id
});
}
}
return users;
}
Prototype with implementation of this approach (using C#/WatiN) see https://github.com/svejdo1/ShadowApi. It is also allowing dynamic update of Facebook connector that is retrieving a list of your contacts.
Try /me/taggable_friends?limit=5000 using your JavaScript code
Or
try the Graph API:
https://graph.facebook.com/v2.3/user_id_here/taggable_friends?access_token=
If you are still struggling with this issue on a development mode.
Follow the same process as mentioned below:
create a test app of your main app,
create test users, automatically install app for test users and assign them 'user_friend' permission.
Add your test users as a friend with each other.
I followed the same process after going through alot of research and finally it worked.
In the Facebook SDK Graph API v2.0 or above, you must request the user_friends permission from each user in the time of Facebook login since user_friends is no longer included by default in every login; we have to add that.
Each user must grant the user_friends permission in order to appear in the response to /me/friends.
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.loginBehavior = FBSDKLoginBehavior.web
fbLoginManager.logIn(withReadPermissions: ["email","user_friends","public_profile"], from: self) { (result, error) in
if (error == nil) {
let fbloginresult : FBSDKLoginManagerLoginResult = result!
if fbloginresult.grantedPermissions != nil {
if (fbloginresult.grantedPermissions.contains("email")) {
// Do the stuff
}
else {
}
}
else {
}
}
}
So at the time of Facebook login, it prompts with a screen which contain all the permissions:
If the user presses the Continue button, the permissions will be set. When you access the friends list using Graph API, your friends who logged into the application as above will be listed
if ((FBSDKAccessToken.current()) != nil) {
FBSDKGraphRequest(graphPath: "/me/friends", parameters: ["fields" : "id,name"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil) {
print(result!)
}
})
}
The output will contain the users who granted the user_friends permission at the time of login to your application through Facebook.
{
data = (
{
id = xxxxxxxxxx;
name = "xxxxxxxx";
}
);
paging = {
cursors = {
after = xxxxxx;
before = xxxxxxx;
};
};
summary = {
"total_count" = 8;
};
}

Firebase automatic login after reloading Ionic app/page

Back when I was using Parse, it seemed like the SDK would store the session data locally and the user didn't have to log in again after refreshing the page (or exiting the mobile app). This doesn't seem to be the case with Firebase/Angularfire; everytime I refresh my web page, the authentication data gets lots. This seems like really basic and important functionality that I would be surprised the awesome people at Firebase haven't implemented. Am I missing something?
For completeness; here is my code in app.run():
// ASG june 2016 - Upgrade firebase SDK
firebase.initializeApp(FirebaseConfig);
// login as anonymous if not already logged in
var currentUser = $firebaseAuth().$getAuth();
if (currentUser) {
console.log("Signed in as:", currentUser);
} else {
console.log("Not logged in; going to log in as anonymous");
$firebaseAuth().$signInAnonymously().then(function(authData) {
console.log("Signed in anonymously as:", authData.uid);
}).catch(function(error) {
console.error("Anonymous authentication failed:", error);
});
}
// register the on auth callback
$firebaseAuth().$onAuthStateChanged(function(authData) {
if (authData) {
console.log("Logged in as:", authData.uid);
if(typeof($rootScope.userProfile) == "undefined"){
$rootScope.userProfile = FirebaseProfileService.getUserProfile(authData.uid, false);
}
}
});
Firebase absolutely presists authData and has a lot of goodness you hardly find elsewhere. Therefore, I don't see any logical reason behind calling getAuth() here as you can easily get the authData from the onAuthStateChanged listener. In this case, you may need to remove your operations of getting currentUser using getAuth() and move your ELSE condition to onAuthStateChanged if you want to sign up users as anonymous in case no AuthData was found, and then you will be good to go, I hope. Hope that works.
The auth token is persisted between page/app reloads. But it will often need to get a new refresh token when the page reloads, which requires a round-trip to the Firebase servers. Since this takes time, the initial getAuth() may return null while that process is ongoing.
var currentUser;
$firebaseAuth().$onAuthStateChanged(function(authData) {
if (authData) {
console.log("Logged in as:", authData.uid);
currentUser = authData.currentUser;
if(typeof($rootScope.userProfile) == "undefined"){
$rootScope.userProfile = FirebaseProfileService.getUserProfile(authData.uid, false);
}
}
else {
console.log("Not logged in; going to log in as anonymous");
currentUser = null;
$firebaseAuth().$signInAnonymously().catch(function(error) {
console.error("Anonymous authentication failed:", error);
});
}
});

Facebook Graph API v2.0+ - /me/friends returns empty, or only friends who also use my application

You will be able to pull the list of friends who have authorised the app only.
The apps that are using Graph API 1.0 will be working till April 30th, 2015 and after that it will be deprecated.
See the following to get more details on this:
User Friends
Facebook Application Development FAQ
In Swift 4.2 and Xcode 10.1:
If you want to get the friends list from Facebook, you need to submit your app for review in Facebook. See some of the Login Permissions:
Login Permissions
Here are the two steps:
1) First your app status is must be in Live
2) Get required permissions form Facebook.
1) Enable our app status live:
Go to the apps page and select your app
https://developers.facebook.com/apps/
Select status in the top right in Dashboard.
Submit privacy policy URL
Select category
Now our app is in Live status.
One step is completed.
2) Submit our app for review:
First send required requests.
Example: user_friends, user_videos, user_posts, etc.
Second, go to the Current Request page
Example: user_events
Submit all details
Like this submit for all requests (user_friends , user_events, user_videos, user_posts, etc.).
Finally submit your app for review.
If your review is accepted from Facebook's side, you are now eligible to read contacts, etc.
As Simon mentioned, this is not possible in the new Facebook API. Pure technically speaking you can do it via browser automation.
this is against Facebook policy, so depending on the country where you live, this may not be legal
you'll have to use your credentials / ask user for credentials and possibly store them (storing passwords even symmetrically encrypted is not a good idea)
when Facebook changes their API, you'll have to update the browser automation code as well (if you can't force updates of your application, you should put browser automation piece out as a webservice)
this is bypassing the OAuth concept
on the other hand, my feeling is that I'm owning my data including the list of my friends and Facebook shouldn't restrict me from accessing those via the API
Sample implementation using WatiN:
class FacebookUser
{
public string Name { get; set; }
public long Id { get; set; }
}
public IList<FacebookUser> GetFacebookFriends(string email, string password, int? maxTimeoutInMilliseconds)
{
var users = new List<FacebookUser>();
Settings.Instance.MakeNewIeInstanceVisible = false;
using (var browser = new IE("https://www.facebook.com"))
{
try
{
browser.TextField(Find.ByName("email")).Value = email;
browser.TextField(Find.ByName("pass")).Value = password;
browser.Form(Find.ById("login_form")).Submit();
browser.WaitForComplete();
}
catch (ElementNotFoundException)
{
// We're already logged in
}
browser.GoTo("https://www.facebook.com/friends");
var watch = new Stopwatch();
watch.Start();
Link previousLastLink = null;
while (maxTimeoutInMilliseconds.HasValue && watch.Elapsed.TotalMilliseconds < maxTimeoutInMilliseconds.Value)
{
var lastLink = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& l.Text != null
).LastOrDefault();
if (lastLink == null || previousLastLink == lastLink)
{
break;
}
var ieElement = lastLink.NativeElement as IEElement;
if (ieElement != null)
{
var htmlElement = ieElement.AsHtmlElement;
htmlElement.scrollIntoView();
browser.WaitForComplete();
}
previousLastLink = lastLink;
}
var links = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& l.Text != null
).ToList();
var idRegex = new Regex("id=(?<id>([0-9]+))");
foreach (var link in links)
{
string hovercard = link.GetAttributeValue("data-hovercard");
var match = idRegex.Match(hovercard);
long id = 0;
if (match.Success)
{
id = long.Parse(match.Groups["id"].Value);
}
users.Add(new FacebookUser
{
Name = link.Text,
Id = id
});
}
}
return users;
}
Prototype with implementation of this approach (using C#/WatiN) see https://github.com/svejdo1/ShadowApi. It is also allowing dynamic update of Facebook connector that is retrieving a list of your contacts.
Try /me/taggable_friends?limit=5000 using your JavaScript code
Or
try the Graph API:
https://graph.facebook.com/v2.3/user_id_here/taggable_friends?access_token=
If you are still struggling with this issue on a development mode.
Follow the same process as mentioned below:
create a test app of your main app,
create test users, automatically install app for test users and assign them 'user_friend' permission.
Add your test users as a friend with each other.
I followed the same process after going through alot of research and finally it worked.
In the Facebook SDK Graph API v2.0 or above, you must request the user_friends permission from each user in the time of Facebook login since user_friends is no longer included by default in every login; we have to add that.
Each user must grant the user_friends permission in order to appear in the response to /me/friends.
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.loginBehavior = FBSDKLoginBehavior.web
fbLoginManager.logIn(withReadPermissions: ["email","user_friends","public_profile"], from: self) { (result, error) in
if (error == nil) {
let fbloginresult : FBSDKLoginManagerLoginResult = result!
if fbloginresult.grantedPermissions != nil {
if (fbloginresult.grantedPermissions.contains("email")) {
// Do the stuff
}
else {
}
}
else {
}
}
}
So at the time of Facebook login, it prompts with a screen which contain all the permissions:
If the user presses the Continue button, the permissions will be set. When you access the friends list using Graph API, your friends who logged into the application as above will be listed
if ((FBSDKAccessToken.current()) != nil) {
FBSDKGraphRequest(graphPath: "/me/friends", parameters: ["fields" : "id,name"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil) {
print(result!)
}
})
}
The output will contain the users who granted the user_friends permission at the time of login to your application through Facebook.
{
data = (
{
id = xxxxxxxxxx;
name = "xxxxxxxx";
}
);
paging = {
cursors = {
after = xxxxxx;
before = xxxxxxx;
};
};
summary = {
"total_count" = 8;
};
}

CakePHP 2.3.1 Facebook authentication

I'm using CakePHP 2.3.1 and this plugin: https://github.com/webtechnick/CakePHP-Facebook-Plugin to implement a facebook authentication. I followed this screen cast http://tv.cakephp.org/video/webtechnick/2011/01/12/nick_baker_--_facebook_integration_with_cakephp but it doesn't work, I can't receive the Facebook user information. I mean $this->Connect->user() always return null.
First make sure your user as granted access to your app. Then make a call to retrieve personal details through the api(/me) => $this->Connect->user()
Personally, I use this
public function beforeFilter(){
if($this->Connect->FB->getUser() != 0){
$this->set('facebookUser', $this->Connect->user());
}
Initiating ConnectComponent will populate (or not) the Auth Session. If no id is to be found, redirect user to a login dialog.
Call this method from beforefilter..and save the post data received in some variable like fb_data here.
protected function _valdiateFbRequest() {
if (!isset($this->request->data['signed_request'])) {
// not a valid request from fb
// throw exception or handle however you want
return;
}
$this->signedRequest = $this->request->data['signed_request'];
$this->fb_data=$this->Connect->registrationData(); //save fb data
unset($this->request->data['signed_request']);
if (empty($this->request->data)) {
$this->Security->csrfCheck = false;
}
// validate the request
}
