Getting an Error - Trying to show wall on my website - facebook

I'm getting the error below for the graph API call:
https://graph.facebook.com/[MYID]/feed?limit=100&access_token=[TOKEN]
{
"error": {
"message": "SETTINGS: Unrecognized pref_type 0 for NullProfileSettings pref name default_non_connection_tab.",
"type": "Exception"
}
}

You should check and recheck your app id.
I had a same problem for few days untill I realized that the app id was wrong.
Go to Graph API Explorer in facebook developer page.
Type in your app id and check if in the result is
a) Your page name
b) Id is the same as you typed in. If not then you should use that one instead.
Hope that helps

Facebook API: (#100) No matching user found

I spent whole days to try to figure out this error, I also notice there are similar questions with the same message, but I'm totally not sure I find the answer in there, so if someone could point out or give any tip into my problem, I totally appreciate that.
I'm making the request to send a message from a Facebook page A to a user X (by userId) who makes a comment on a post of FB Page A, through a testing FB App name MyApp. I am trying this on Facebook Graph Explorer.
I got the user Id by fetch the list of comments in a post in the Facebook Page, but I totally could not send the message.
Here is the error
{
"error": {
"message": "(#100) No matching user found",
"type": "OAuthException",
"code": 100,
"error_subcode": 2018001,
"fbtrace_id": "H3yMO0RWaDy"
}
}
Here is the my track
MyApp has been setup webhook OK, because it is not published yet for the testing purpose (unapproved app), so I have to add the user X account into tester pool of MyApp (the message that I try to send is also this user X)
I logged into user X to make a comment on a post in the FB Page A
On Graph Explorer, I selected Application: MyApp, and get Page Access Token of FB Page A, I performed two following requests
3.1 /{page_id}_{post_id}?fields=comments
With this, I can get the list of existing comments in FB Page A, here is the output:
{
"comments": {
"data": [
{
"created_time": "...",
"from": {
"name": "User X",
"id": "123456789" // this is the user Id that I would take to send the message to
},
"message": "Sample comment from User X",
"id": "..." // {page_id}_{post_id}
}
],
"paging": {
....
}
},
"id": "..." // {page_id}_{post_id
}
}
3.2 {page_id}/messages: I am trying to send a message from FB Page A to user X with the user Id that I got from 3.1 step
recipient: {id: "123456789"} // there seems be a problem with this id that I got from step 3.1, FB cannot find the user id with this number
message: {text: "hello"}
I'm also acknowledged about the app/page scoped id for user.
I have already subscribed MyApp to the FB Page A with API (/{page_id}/subscribed_apps)
Facebook API v2.10
I have no clue what's wrong.
I figured it out. Facebook Messenger Platform use paged scope user id, but what I were using is app scope id. They are different.
Here is official doc from Facebook about how to get the paged scope id
The id must be an ID that was retrieved through the Messenger entry
points or through the Messenger webhooks (e.g., a person may discover
your business in Messenger and start a conversation from there.
These IDs are page-scoped IDs (PSID). This means that the IDs are
unique for a given page.
If you have an existing Facebook Login integration, user IDs are
app-scoped and will not work with the Messenger platform.
The solution is subscribing MyApp to the FB Page (what I've already done) to get the webhook to work, where I will get the page scope id from the message of user.
Furthermore, detail of how to setup the subscription found here

Graph API tells me an object doesn't exist while it does

I'm starting to create a little app to get the names associated with Facebook IDs for a bigger project. I just started to use the Facebook API and it's giving me weird results. Most of the time, everything works fine. I use this code (I'm using Python, but that doesn't really matter here since it's the Facebook API that is causing the problem) :
def downloadString(url, params):
cookie = {}
data = requests.get(url,cookies=cookie,params=params)
return data.text
url = "https://graph.facebook.com/v2.6/"
id = "afriendidhere"
dl = basics.downloadString(url + id, {"access_token":accesstoken})
res = json.loads(dl)
As I said, most of the time, it works just fine, giving me the name of the given person. Though, for two people in my friends list, I get the following message :
{
"error": {
"message": "Unsupported get request. Object with ID 'theid' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api",
"type": "GraphMethodException",
"code": 100,
"fbtrace_id": "FTfrh78XjW/"
}
}
I don't understand why. The person with this id does exist, since I can access the page http://facebook.com/messages/theid and it's giving me my conversation history with this user. It's always the same people who cause the error, everyone else works perfecty.
Does anyone know why ?
You are only supposed to get data from users who authorized your App. Authorized them, get their App Scoped ID and name with the /me endpoint. More information: https://developers.facebook.com/docs/graph-api/reference/v2.6/user
The solution for me was to publish the page in settings
Page Visibility --> Publish
Save changes
Try removing any visibility limitations from your Page's settings (such as country restrictions etc)

How to get the result in Facebook Graph Api Explorer.? Getting error message (#15) This method must be called with an app access_token

I was Unable to get the search result in Facebook Graph Api Explorer For Topic search API. I am getting the following error. I also have the access token included.
{
"error": {
"message": "(#15) This method must be called with an app access_token.",
"type": "OAuthException",
"code": 15,
"fbtrace_id": "CJiZqVSATXu"
}
}
Well, the error message actually contains the problem. You're not using an App Access Token, but seemingly an User Access Token (from the Access Token structure in your screenshot).
You must select an app of yours in the upper right Applications dropdown, and then select Get App Token in the dropdown below.
Still, that will probably not help much in this case. Are you aware that only whitelisted apps can use the Topic Search API?

Facebook API Video Views

I want to get the views of a video on my Facebook page.
My request:
{object-id}/insights/post_video_views_organic
But instead of data I get the following error back:
{
"error": {
"message": "(#100) Tried accessing nonexisting field (insights) on node type (Video)",
"type": "OAuthException",
"code": 100
}
}
I haven´t really worked with the Facebook API in the past so I cant really translate this error message.
(I am using the Graph API Explorer)
Try adding the id of your facebook page (which you can retrieve through the Graph API or here) to the start of the object id, followed by an underscore ('_') then the object id of the video.
Instead of "{object-id}/insights/post_video_views_organic".
Use "{post-id}/insights/post_video_views_organic" . You will get the metrics.
The "post-id" is post id of that video post.

Unusual behavior of facebook grap API ("type": "GraphMethodException", "code": 100)

I am having some unusual errors while fetching some data for some users via graph API.
As for example w all know we can get basic user info via graph.facebook.com/username
And it works. But it is not working for some users. Like the user www.facebook.com/sanzida.tanzum is a valid facebook user. So, we should get her basic info via graph.facebook.com/sanzida.tanzum. But when you will try that, you will get the error
{
"error": {
"message": "Unsupported get request.",
"type": "GraphMethodException",
"code": 100
}
}
And it is not a permission issue because use user herself gets the same error when she try to retrive her own data via graph API. Actually the user sanzida.tanzum is invisible to graph API. For example user sanzida.tanzum is on my friend list. You can check here. my friendlist.(it is public). But when I retrive my friendlist via graph API, my friendlist is shown excluding the user sanzida.tanzum ! But she is in my friendlist!
I have tried to contact facebook for this matter because I did not find any doccument related to this matter. They replied it is usual. (probably they did not read my mail at all. I am including the email conversation with facebook)
Hi তৌফিক,
They are getting errors because they are not you... they dont have
permissions to see the same things you do. They might also be missing
an access token. Either way: no bug here.
Thanks,

Authentication Vulnerability Scope: Platform Developer API Title:
Unusual bug in facebook graph API Product / URL:
https://graph.facebook.com/sanzida.tanzum Description and Impact: I
was doing some graph API calls for testing purpose. Mostly I was doing
mostly user profile calls. (https://graph.facebook.com/exampleuser)
Somehow I realized facebook is giving following errors for some users
even they are on my friendlist. Same thing occurs when they try by
themselves.
As for eample the user "https://www.facebook.com/sanzida.tanzum" is on
my friendlist. (My friendlist is public.You can check if you want.)
So, according to facebook graph API, I can request the user's basic
info using (https://graph.facebook.com/sanzida.tanzum) But it returns
this error:
"{ "error": {
"message": "Unsupported get request.",
"type": "GraphMethodException",
"code": 100 } }"
Actually graph API can't access nothing of this user. Another
example.. When I request my friendlist via graph API , All friends of
my friendlist is shown except the user (sanzida.tanzum). But she is in
my friendlist! check here (my friendlist is public)
"https://www.facebook.com/toufiqueimam/friends". So why is this
happening only for few users?
Just now I got confirmation that the user herself gets the same error
if she tries to access (https://graph.facebook.com/sanzida.tanzum)
{ "error": {
"message": "Unsupported get request.",
"type": "GraphMethodException",
"code": 100 } }
Reproduction Instructions / Proof of Concept: Reproduction: first go
to https://www.facebook.com/sanzida.tanzum You will see it is a valid
profile. Now try https://graph.facebook.com/sanzida.tanzum You will
get following error
{ "error": {
"message": "Unsupported get request.",
"type": "GraphMethodException",
"code": 100 } }
This isn't a bug, the error means that the data you're trying to access is not accessible to you, does not exist, has been deleted, is not available because you haven't provided an access token from a user who can see it, etc.
See this answer for an example of this error message in relation to Facebook pages: https://stackoverflow.com/a/6847088/21062 - the same is true when trying to access user profiles if that user has blocked you, blocked your app, disabled their account or disabled all apps from accessing their information.
Just an FYI, I ran into this problem, and it wasn't because the user had blocked all applications. In my scenario, my application was attempting to force-convert Facebook's 64 bit integers into a 53 bit JavaScript integer (Node application). It was mangling the value, so when I was making the Facebook GET Request later on in my application lifecycle, I was doing so with the mangled value, and Facebook was trying to tell me "Um, this UserId doesn't exist".
So in my application, I had to use the Node Big-integer add-on, along with the Mongoose mongoose-long plugin for my Mongodb.
Long story short, if you are converting the UserId to it's native 64 bit integer, don't do so unless the intger type in your application is at least 64 bits.
