Hello,
I am trying to implement this bundle to use social logins for my app. I want to implement facebook and google.
I follow the recommended steps but facebook gives me "Something went wrong. We are working on it," and google is getting stuck after the user selects a google account and nothing happens.
With google I think the error happens in fetchAccessToken in authenticate method because I have tried dd() before it and it works. However after this method call the app is stuck in a forever loop
Here is my code:
GoogleController:
<?php
namespace App\Controller;
use KnpU\OAuth2ClientBundle\Client\ClientRegistry;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
class GoogleController extends AbstractController
{
/**
* Link to this controller to start the "connect" process
*
* @Route("/connect/google", name="connect_google_start")
*/
public function connectAction(ClientRegistry $clientRegistry)
{
// will redirect to google!
return $clientRegistry
->getClient('google') // key used in config/packages/knpu_oauth2_client.yaml
->redirect([
'openid'
]);
}
/**
* After going to google, you're redirected back here
* because this is the "redirect_route" you configured
* in config/packages/knpu_oauth2_client.yaml
*
* @Route("/connect/google/check", name="connect_google_check")
*/
public function connectCheckAction(Request $request, ClientRegistry $clientRegistry)
{
// leave this method blank and create a Guard authenticator
}
}

configure your clients as described here: https://github.com/knpuniversity/oauth2-client-bundle#configuration
Any help will be much appreciated! Thank you
