Can't login via sample index.php

[zlyfer]

Hey,
I am using PHP Slim and I embedded your sample index.php.
However it seems like that the authentification doesn't work.
I used an echo "hi"; and print_r($oauth2); to print where the page is stuck and it seems like the page never gets to the user informmation retrievement.

// ...
  if ($oauth2->isRedirected() === false) { // Did the client already logged in ?
        // The parameters can be a combination of the following: connections, email, identity or guilds
        // More information about it here: https://discordapp.com/developers/docs/topics/oauth2#shared-resources-oauth2-scopes
        // The others parameters are not available with this library
        $oauth2->startRedirection(['identify', 'guilds']);
        print_r($oauth2);
        echo "hi";
    } else {
// ...

Result is:

Xwilarg\Discord\OAuth2 Object ( [_clientId:Xwilarg\Discord\OAuth2:private] => xxxxxxxxxxxxxxxxxx [_secret:Xwilarg\Discord\OAuth2:private] => xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx [_redirectUrl:Xwilarg\Discord\OAuth2:private] => http://localhost:8090/ [_accessToken:Xwilarg\Discord\OAuth2:private] => ) hi
