Laravel 5 authentication error?

Question

Laravel

Hello!
Who got into such an error when working with Socialite Providest (Not pure socialite, but Socialite Providers).
Used vk.
This error has not been observed until today:
Argument 1 passed to Illuminate\Auth\SessionGuard::login() must implement interface Illuminate\Contracts\Auth\Authenticatable, null given, called in D:\openserver\domains\make.ru\vendor \laravel\framework\src\Illuminate\Auth\AuthManager.php on line 294 and defined

public function callback(SocialAccountService $service, $provider)
    {

        $driver   = Socialite::driver($provider);
        $user = $service->createOrGetUser($driver, $provider);
        \Auth::login($user, true);
        return redirect()->intended('/');

    }

As you can see from the code, the error is most likely in the drain
. the called method does not satisfy the interface. Consequently, the $user variable does not get what the login method expects. I think you need to dig in this direction.
