error: Invalid OAuth access token signature.

[sebpiq]

Hi!

I am trying to get started; and I have this very simple code :

var Facebook = require('facebook-node-sdk')

var facebook = new Facebook({
    appID: 'my app id',
    secret: 'my app secret'
})

facebook.api('/me', function(err, data) {
  console.log(err, data)
})

I don't know what's the problem, but I keep getting this error :

{ result: 
   { error: 
      { message: 'Invalid OAuth access token signature.',
        type: 'OAuthException',
        code: 190 } },
  code: 0,
  message: 'Invalid OAuth access token signature.' }

did I miss something very basic?

I get the same error and I've tried resetting the secret key without any luck

[BaseInfinity]

Don't forget to set your access token.

var facebook = new Facebook({
    appID: 'my app id',
    secret: 'my app secret'
}).setAccessToken('access token');

[sebpiq]

@BaseInfinity how do you get this access token? In my app page I have only the id and the secret.

[awm33]

Had this issue too. Did what @BaseInfinity said.

@sebpiq Go to https://developers.facebook.com/docs/facebook-login/access-tokens/

For an App access token

GET /oauth/access_token?
client_id={app-id}
&client_secret={app-secret}
&grant_type=client_credentials

[Troush]

https://developers.facebook.com/docs/howtos/login/login-as-app/:

“Because it requires you to include your App Secret you should not attempt to make this call client-side as that would expose this secret to all your app users. It is important that your App Secret is never shared with anyone. For this reason, this call should be performed server-side”

And for the app access token, it’s the same – you should never use it client-side, because every user could spot it there and then start using it to perform actions on behalf of your app (or change many of your app’s settings).

If you have a server-side part to your application, you can simply “build” the app access token there yourself, concatenating app id and secret with a pipe symbol, app_id|app_secret.

[gilesgoodwin]

The issue is the param 'appID' should be 'appId':
appID: 'my app id',

[mjpizz]

Just ran into this too - it looks like the README example has the wrong capitalization

[paulbrzeski]

OMG! Thanks for pointing out the capitalization issue!

I was grinding my teeth dreading having to jerry rig some kind of GET token request and wondered why this lib didn't just do it... this explanation makes a lot more sense :P

[KouSyurei]

I don't know me by AccessToken getCurrentAccessToken () method to get the token is a token of the APP or the user's token, through "https://graph.facebook.com/debug_token? Access_token = {My AppId} | {CMy AppSecret} & input_token = {AccessToken. GetCurrentAccessToken () access token} "the interface returned My token validation error of this information.

1. Can you describe the situation where you have this problem?

2. What is your version of flutter_facebook_login?

3. Can you post your source code?
