Facebook API error 191

Question

I\'m trying to integrate my project with Facebook. I\'m taking baby steps at first and just trying to login, get a Facebook session, and get some user data. I\'m developing

Answer 1

I fixed this by passing the redirect url to the FacebookRedirectLoginHelper::getAccessToken() in my callback function:

Changing from

try {
        $accessToken = $helper->getAccessToken();
}
...

to

try {
        $accessToken = $helper->getAccessToken($fbRedirectUrl);
}
...

I am developing on a vagrant box, and it seems FacebookRedirectLoginHelper::getCurrentUrl() had issues generating a valid url.
