I have written sample echo message bot using facebook messenger api and wit.ai actions.
My message from facebook page is received and the proper action function defined using wit api's is also getting called. However
while returning the response, i am getting followin error as -
Oops! An error occurred while forwarding the response to : Error: (#100) Param message[text] must be a UTF-8 encoded string
at fetch.then.then.json (/app/index.js:106:13)
at process._tickCallback (internal/process/next_tick.js:103:7)
Here is the function which is used to return the response -
const fbMessage = (id, text) => {
const body = JSON.stringify({
recipient: { id },
message: { text },
});
const qs = 'access_token=' + encodeURIComponent(FB_PAGE_ACCESS_TOKEN);
return fetch('https://graph.facebook.com/v2.6/me/messages?' + qs, {
method: 'POST',
headers: {'Content-Type': 'application/json; charset=UTF-8'},
body
})
.then(rsp => rsp.json())
.then(json => {
if (json.error && json.error.message) {
throw new Error(json.error.message);`enter code here`
}
return json;
});
};
I have copied this function from the messenger.js file from the documentation since i am just trying the POC.
I checked the values for text and id in this function and verified using console.log statements and those are coming properly.
Can some experts help me to solve this error?
Note - I tried encoding the text using text.toString("utf8"); but it returns the encoding string as [object object] and thats the
response i get from bot. so it doesnt work.
Get the latest code from node-wit, there is a change in facebook id usage,
According to Facebook:
On Tue May 17 format of user and page ids delivered via webhooks will
change from an int to a string to better support default json encoder
in js (that trims long ints). Please make sure your app works with
string ids returned from webhooks as well as with ints.
Still you are getting issue with the api try to add if(event.message && !event.message.is_echo) condition as shown in below code.
// Message handler
app.post('/webhook', (req, res) => {
const data = req.body;
if (data.object === 'page') {
data.entry.forEach(entry => {
entry.messaging.forEach(event => {
if (event.message && !event.message.is_echo) {
const sender = event.sender.id;
const sessionId = findOrCreateSession(sender);
const {text, attachments} = event.message;
if (attachments) {
fbMessage(sender, 'Sorry I can only process text messages for now.')
.catch(console.error);
} else if (text) {
wit.runActions(
sessionId, // the user's current session
text, // the user's message
sessions[sessionId].context // the user's current session state
).then((context) => {
console.log('Waiting for next user messages');
sessions[sessionId].context = context;
})
.catch((err) => {
console.error('Oops! Got an error from Wit: ', err.stack || err);
})
}
} else {
console.log('received event', JSON.stringify(event));
}
});
});
}
res.sendStatus(200);
});

When user register from client side(mobile app) , user automatically login app i dont want auto login so, I did some research, I had to use a firebase cloud function to solve this.
But I get a few errors when calling the function , how can i fix these errors
First error :
Access to XMLHttpRequest at 'https://***.cloudfunctions.net/createUser' from origin 'http://localhost:8100' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
second error :

Third Error

cloud function :
const functions = require('firebase-functions');
const cors = require('cors')({ origin: true });
const admin = require('firebase-admin')
admin.initializeApp();
exports.createUser = functions.https.onRequest((request, response) => {
return cors(req, res, () => {
if (request.method !== "POST") {
response.status(405).send("Method Not Allowed");
} else {
let body = request.body;
const email = body.email;
const password = body.password;
admin.auth().createUser({
email: email,
emailVerified: false,
password: password,
})
.then((userRecord) => {
return response.status(200).send("Successfully created new user: " +userRecord.uid);
})
.catch((error) => {
return response.status(400).send("Failed to create user: " + error);
});
}
})
});
client side :
signUp(email,password){
let body = {
email : email,
password : password
}
this.http.post(
'https://****.cloudfunctions.net/createUser',
body
).subscribe(a=>{console.log("Work")});
}
EDIT (new cloud function code) :
1st and 2nd bug fixed 3 still continues but I can create users.
exports.createUser = functions.https.onRequest((req, res) => {
res.set('Access-Control-Allow-Origin', '*');
res.set('Access-Control-Allow-Methods', ' POST, OPTIONS');
res.set('Access-Control-Allow-Headers', '*');
if (req.method === 'OPTIONS') {
res.end();
}
else {
let body = req.body;
console.log(body.email)
console.log("body.password")
const email = body.email;
const password = body.password;
admin.auth().createUser({
email: email,
emailVerified: false,
password: password,
})
.then((userRecord) => {
return res.status(200).send("Successfully created new user: " +userRecord.uid);
})
.catch((error) => {
return res.status(400).send("Failed to create user: " + error);
});
}
});
Cross origin error has many reason, first problem is your current url that probably like a ads url, please change the url pattern and clear browser cache. If you are using a VPN turn off it. The Chrome blocks url that contain ads url. This problem is not happen on production environment.
If your problem not fixed with top solution, use chrome in security disable mode.
Open start menu and type chrome.exe --disable-web-security and
make sure that this headers set in your backend
header('Access-Control-Allow-Origin: *');
header('Access-Control-Request-Method:*');
header('Access-Control-Allow-Headers: Origin,token, Authorization, X-Requested-With, Content-Type, Accept');
header('Access-Control-Allow-Credentials: true');
I copied the following code from Amazon Cognito Vuex Module examples to my Vue.js app:
axios.interceptors.request.use(async config => {
const response = await store.dispatch('getUserSession');
if (response && response.accessToken && response.accessToken.jwtToken) {
config.headers.awsToken = response.accessToken.jwtToken;
}
return config;
});
and expected to see in the request headers something like
awsToken: AzWDF....
, but actually I am getting:
Why 'awstoken' goes to 'Access-Control-Request-Headers' and why it does not have a value?
I also tried
config.headers.common['awsToken'] = response.accessToken.jwtToken;
but with the same result.
It is not a problem of AWS, because response.accessToken.jwtToken has a valid non-empty value.
EDIT1: and even this example does not work in my app and gives the same result:
axios.interceptors.request.use(config => {
config.headers['Authorization'] = 'Bearer XYZ';
return Promise.resolve(config);
},
(error) => {
return Promise.reject(error);
});
EDIT2: I found similar post.
I'm trying to create a Facebook chatbot with NodeJS, Express, and a Heroku server.
I created my webhook on heroku and had it verified and saved by facebook. I then started adding code that would reply to the incoming messages and I can't seem to get it connected. It keeps saying "Error, wrong validation token" when I try to load my webhook in my browser. And when I try to send my bot a message I get no response. Even though I already had it verified and didn't change the code.
Here is my code:
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
var port = process.env.PORT || 3000;
// body parser middleware
app.use(bodyParser.urlencoded({ extended: true }));
// test route
//app.get('/', function (req, res) { res.status(200).send('Hello world!') });
app.get('/', function (req, res) {
if (req.query['hub.verify_token'] === '8FKU9XWeSjnZN4ae') {
res.send(req.query['hub.challenge']);
}
res.send('Error, wrong validation token');
})
app.post('/', function (req, res) {
messaging_events = req.body.entry[0].messaging;
for (i = 0; i < messaging_events.length; i++) {
event = req.body.entry[0].messaging[i];
sender = event.sender.id;
if (event.message && event.message.text) {
text = event.message.text;
sendTextMessage(sender, "Text received, echo: "+ text.substring(0, 200));
}
}
res.sendStatus(200);
});
// error handler
app.use(function (err, req, res, next) {
console.error(err.stack);
res.status(400).send(err.message);
});
app.listen(port, function () {
console.log('Listening on port ' + port);
});
var token = <myToken>;
function sendTextMessage(sender, text) {
messageData = {
text:text
}
request({
url: 'https://graph.facebook.com/v2.6/me/messages',
qs: {access_token:token},
method: 'POST',
json: {
recipient: {id:sender},
message: messageData,
}
}, function(error, response, body) {
if (error) {
console.log('Error sending message: ', error);
} else if (response.body.error) {
console.log('Error: ', response.body.error);
}
});
}
So I'm confused as to why nothing is happening and why I'm getting that error. I feel like I'm missing a whole step. I am following this tutorial by the way: https://developers.facebook.com/docs/messenger-platform/quickstart
Any help is appreciated. Thanks!
Edit: Here are my heroku logs
Do not post your full access tokens here!
Have you tested the output of the challenge? Since it's just a GET and you know all values you can try it yourself: your-app-domain.com/your-callback-url?hub_mode=subscribe&hub_verify_token=the_token_you_set_in_your_app_config&hub_challenge=ping which sould print 'ping' if everything work fine.
Make sure you add sendStatus(200) to the hub challenge response, too.
You need to subscribe your page to the app first. To do so make a POST request to /your-page-id/subscribed_apps which should return "success". You can make a GET request to the same endpoint afterwards to double check your app is subscribed to your page
You did not mention which events you subscribed to (needs to be message_deliveries, messages, messaging_optins, messaging_postbacks)
Make sure the webhooks tab in your app dashboard now says "complete"
Test again
You are actually using "request" but you are never importing it anywhere. Here's how to fix it:
var request = require("request")
Once you have added that to your index.js or app.js file (basically whatever this file is), make sure you do:
npm install request --save
This should fix it. Unfortunately, Heroku doesn't error out and say that it does not know what "request" is and that's why it was so hard to figure this out in the first place!
I'm trying to send a photo using facebook node sdk module to a page. https://github.com/Thuzi/facebook-node-sdk/
I'm able to post to the page wall or to uplaod from an url. But i have a problem trying to uplaod photo from data.
That is how i connected :
FB.api('oauth/access_token', {
client_id: clientid,
client_secret: clientsecret,
redirect_uri: redirecturi,
code: code,
scope: scope,
fileUpload : true,
}, function (resf) { ...}
I get the good access token like this :
FB.api('/me/accounts', function (resf) {
if (!resf || resf.error) {
console.log(!resf ? 'error occurred' : resf.error);
return;
}
for (var i = 0; i < resf.data.length; i++) {
if (resf.data[i].id == pageid)
{
resf.data[i]. access_token
}
});
And i try to upload the photo :

FB.api(pageid + '/photos', 'post', { message: body, url: 'url_image', }, function (resf) {
if (!resf || resf.error) {
console.log(!resf ? 'error occurred' : resf.error);
return;
}
console.log( resf);
res.send(resf);
});
What did i forget ?
Does multipart upload is allowing with this module : https://github.com/Thuzi/facebook-node-sdk/
It does not appear to support multipart. You could do it manually with the request module:
var request = require('request');
// ....
var access_token = 'abc123',
pageid = 'me',
fburl = 'https://graph.facebook.com/'
+ pageid
+ '/photos?access_token='
+ access_token,
req,
form;
req = request.post(fburl, function(err, res, body) {
if (err)
return console.error('Upload failed:', err);
console.log('Upload successful! Server responded with:', body);
});
form = req.form()
// append a normal literal text field ...
form.append('message', 'My photo!');
// append a file field by streaming a file from disk ...
form.append('source', fs.createReadStream(path.join(__dirname, 'photo.jpg')));
// or append a Buffer ...
form.append('source', someBuffer);
// or append the contents of a remote url ...
form.append('source', request('http://google.com/doodle.png'));
Example (from mscdex) above works for:
form.append('source', requestLib('<imageURL>'));
Gives response:
{"id":"756317401077924","post_id":"100000990137087_756310827745248"}
Also works for:
form.append('source', fs.createReadStream('<imagepath>'));
Gives response:
{"id":"756328687743462","post_id":"100000990137087_756310827745248"}
This is probably all I need. Thanks mscdex, very helpful. But out of curiosity, when I replaced it with an image buffer:
form.append('source', imageBuffer);
It gives the same error as OP (even when using the same image string as OP):
{"error":{"message":"(#324) Requires upload file","type":"OAuthException","code":324}}
Why? My guess is Facebook wants a specific format for an encoded image.
js.I am trying to create a file upload using node.js and mongodb.I am getting timeout error in posting data.The code that i use is:
app.post('/photos/new', function(req, res) {
var photo = new Photo();
req.form.complete(function(err, fields, files) {
if(err) {
next(err);
} else {
ins = fs.createReadStream(files.file.path);
ous = fs.createWriteStream(__dirname + '/static/uploads/photos/' + files.file.filename);
util.pump(ins, ous, function(err) {
if(err) {
next(err);
} else { photos.save({
filename: files.file.filename,
file: files.file.path
}, function(error, docs) {
res.redirect('/photos');
});
}
});
//console.log('\nUploaded %s to %s', files.photo.filename, files.photo.path);
//res.send('Uploaded ' + files.photo.filename + ' to ' + files.photo.path);
}
});
});
I get the following error when i click on the submit button.
Error: Timeout POST /photos/new
at Object._onTimeout (/home/nodeexmple/node_modules/connect-timeout/index.js:12:22)

Please help.
see this answer...
Error: parser error, 0 of 4344 bytes parsed (Node.js)
Also u can use req.clearTimeout() as suggested above by alessioalex.
I belive this part of your code is creating problems that u should avoid.
photos.save({
filename: files.file.filename,
file: files.file.path
}, function(error, docs) {
res.redirect('/photos');
});
Instead use like this:
var post = new Post();
post.filename=files.file.filename;
post.file=files.file.path;
And then something like this:
post.save(function(err) {
if (err)
return postCreationFailed();
req.flash('info', 'photos Succesfully Uploaded');
res.redirect('were u want to redirect');
});
Hope this solves your issue.
You are using the connect-timeout module so that is shows a message to your users in case the page takes more than X seconds to load (server-side).
It's obvious that the upload page might be taking more than that, so what you should do in your upload route is to clear the timeout like this:
app.post('/photos/new', function(req, res) {
req.clearTimeout();
...
Read more about connect-timeout on its github page.
