Socialite показывает ошибку Драйвер [обратный вызов] не поддерживается

Question

Я разрабатываю социальную учетную запись, используя пакет Socialite. Мне удалось войти через Twitter и Google+, но с помощью Facebook я получаю следующее сообщение об ошибке, не знаю, чего не хватает

InvalidArgumentException in Manager.php line 90:
    Driver [callback] not supported.

Вот мой код.. ошибка, возникшая, когда я нажимаю на кнопку входа в Facebook, которая приводит меня к redirectToProvider метод, поэтому ошибка происходит, когда я иду в

Socialite::driver($provider)->stateless()->redirect()

Когда приложение Facebook возвращает URI перенаправления, когда я вижу эту ошибку
