带有Socialite的Laravel 5.3中的SessionGuard.php中的ErrorException（Facebook作为提供者）

Question

I got a Laravel project (v5.3) which needs a login with a custom form and with facebook connect.

So, I use Socialite and it's what I need, however, when I login for first time, the callback doesn't redirect to the view/url that I indicate, instead Laravel shows me the next Exception:

ErrorException in SessionGuard.php line 439: Argument 1 passed to Illuminate\Auth\SessionGuard::login() must implement interface Illuminate\Contracts\Auth\Authenticatable, null given, called in /var/www/vendor/laravel/framework/src/Illuminate/Auth/AuthManager.php on line 294 and defined

This is the code in my custom controller :

public function handleProviderCallback()
{
    try
    {
        $socialUser = Socialite::driver('facebook')->user();

    }catch(\Exception $e)
    {
        return redirect('/');
    }
        $user = User::where('facebook_id', $socialUser->getId())->first();

        if(!$user)
            User::create([
                'facebook_id' => $socialUser->getId(),
                'name' => $socialUser->getName(),
                'email' => $socialUser->getEmail(),
            ]);

            auth()->login($user);
            return redirect()->to('/home');              
}

So, I check my database and the record is there - Ok ...but I'm not in session - wrong ... if I login with facebook again (keeping the record in the database) I login successfully and the error is gone... Ok but at all...

If I do:

dd($user)

I got a null value the first time In the following times I got nothing...the $user var show in blank...

So I think is this line:

auth()->login($user);

And I tried

\Auth::login($user);

but it doesn't work too...

So, what's could be wrong, any configuration in my project? This example I saw it in tutoriales with Laravel 5.3 so I don't understand what's going on :(

Thank you! And sorry for my english! :)

Do this:

if(!$user)
        $user = User::create([
            'facebook_id' => $socialUser->getId(),
            'name' => $socialUser->getName(),
            'email' => $socialUser->getEmail(),
        ]);

I added $user = to your existing code. Because when you do Model::create it returns an object of type Model.
