Auto Login After successful registration in laravel 6 getting an error - laravel

Question

I am getting an error while trying to Auto Login After successful registration in laravel 6 getting the following error.
Argument 1 passed to Illuminate\Auth\SessionGuard::login() must implement interface Illuminate\Contracts\Auth\Authenticatable, null given, called in
My Registercontroller is
class RegisterController extends Controller
{
use RegistersUsers;
protected $redirectTo = RouteServiceProvider::HOME;
public function __construct()
{
$this->middleware('guest');
// $this->middleware(['auth','verified']);
}
protected function validator(array $data)
{
return Validator::make($data, [
'name' => ['required', 'min:3'],
'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
'password' => ['required', 'string', 'min:8', 'confirmed'],
]);
}
protected function create(array $data)
{
$username = slugify($data['name'])."-".mt_rand(10000, 99999);
$user = User::create([
'name' => $data['name'],
'username' => $username,
'email' => $data['email'],
'password' => Hash::make($data['password']),
'email_token' => base64_encode($data['email']),
]);
Auth::loginUsingId($user->id);
}
}
User Model
<?php
namespace App;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use App\Jobs\SendEmailJob;
class User extends Authenticatable implements MustVerifyEmail
{
use Notifiable;
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'email','name','password','username','picture',
'ip_address','email_verified_at','email_token','verified'
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
/**
* The attributes that should be cast to native types.
*
* #var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
function socialProviders(){
return $this->hasMany(socialProvider::class);
}
// This is the code define in the sendEmailVerificationNotification
public function sendEmailVerificationNotification()
{
SendEmailJob::dispatch($this);
}
}

Answer 1

You have overwritten the registration logic, but you have ignored the fact that create method needs to return an instance of App\User - or at least a class that implements Authenticatable.
Take a look at the original logic; you will see that the docblock shows that an instance of App\User is being returned and that the original implementation returns the result of the User::create() call.
To get your custom method working, update it like so:
protected function create(array $data)
{
return User::create([
'name' => $data['name'],
'username' => slugify($data['name'])."-".mt_rand(10000, 99999);,
'email' => $data['email'],
'password' => Hash::make($data['password']),
'email_token' => base64_encode($data['email']),
]);
}
Laravel will take care of logging the user in by default anyway.
