                }else if($user->role_id == 1){

        // return $user;
    } 
}

Can someone please help me I am stuck, I have tried so many things but I am new on coding so maybe you will understand If it is that I am asking too much

Answer 1

App\Models\User must implement the interface/contract Illuminate\Contracts\Auth\Authenticatable.

"If you need to log an existing user instance into your application, you may call the login method with the user instance. The given object must be an implementation of the Illuminate\Contracts\Auth\Authenticatable contract. Of course, the App\User model included with Laravel already implements this interface ..."

Laravel 5.7 Docs - Authentication - Manually Authenticating Users - Other Authentication Methods

Side Note:

The create method of that controller is only for taking an array of data and creating a new User and returning that User instance. Nothing else. The registration flow out of the box calls that method, only to create the user. It then does the login and everything else.
