Authentication failed! Facebook returned an invalid user id

[Steeveuk]

I know this has been posted before, however my issue seems to be different from everyone elses. Basically I have a setup where we have a local, staging and live server and everything connects smoothly on local and staging but live simply keeps getting a fatal exception with this:

Fatal error: Uncaught exception 'Exception' with message 'Authentication failed! Facebook returned an invalid user id.' in /home/dashboard/library/HybridAuth/Hybrid/Auth.php:169 Stack trace: #0 /home/dashboard/library/HybridAuth/Hybrid/Auth.php(55): Hybrid_Auth::initialize('/home/dashb...') #1 /home/dashboard/library/core/UserSocialConnection.class.php(19): Hybrid_Auth->__construct('/home/dashb...') #2 /home/dashboard/public_html/modules/entities/settings/index.php(10): core\UserSocialConnection::get_hybrid_auth(false) #3 {main} thrown in /home/dashboard/library/HybridAuth/Hybrid/Auth.php on line 169

I have changed it from https to http and ensured the base URL is correct. I have also tried multiple configs, permissions and pretty much exhausted every avenue I can think to debug it. I have checked the other threads on here and on Stack overflow to no avail. If anyone has come across this issue before or has any suggestions I am all ears.

Cheers

Weired bug, i cant figure out why

[Steeveuk]

I forgot to post the fix which was because i didn't have trustForwarded set to true. It fixed after that. Hope it helps someone in future!

@Steeveuk So you only had to add a trustForwarded" => true to the Facebook config? Do you also use Hybridauth 2.6.0? For me, it always keeps returning 0 as the user id. :(

if you Amazon Cloud , you may modify as follow:
./Hybrid/thirdparty/Facebook/base_facebook.php
line 1251:
under "protected function getHttpProtocol() {"
return 'https';
or
if (isset($_SERVER['HTTP_CLOUDFRONT_FORWARDED_PROTO'])) { if ($_SERVER['HTTP_CLOUDFRONT_FORWARDED_PROTO'] === 'https') { return 'https'; } return 'http'; }
and also ./config.php,'base_url' changed http to https
or
"base_url" => ($_SERVER['HTTP_CLOUDFRONT_FORWARDED_PROTO'] === 'https')?"https://xxx":"http://xx",

hope it helps you,@Steeveuk

@kocsismate can you change, in 2.6.0, the latest return of function getCurrentUrl() in base_facebook.php with:
var_dump($protocol.$parts['host'].$port.$parts['path'].$query); exit;
And see if the url is fine to you?

I've faced the same issue because the getCurrentUrl() wasn't the same as the base_url.

@Steeveuk you should close this bug as you solved it with trustForwarded.

Unfortunately, I no longer have access to the code for which I needed Hybridauth ^^

in base_facebook.php

  protected function getHttpProtocol() {

    //we are sure is a https request , we use first the Nginx forwarded PROTO OR apache OR cloudflare
        if( (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) AND $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https') 
            OR (isset($_SERVER['REQUEST_SCHEME']) AND $_SERVER['REQUEST_SCHEME'] == 'https')
            OR (isset($_SERVER['HTTP_CF_VISITOR']) AND $_SERVER['HTTP_CF_VISITOR'] == '{"scheme":"https"}')
            )
        {   
         
            return 'https';
        }

        return 'http';
  }
