Laravel 6.5.2 error when registering on overwritten users table - laravel

Question

I have overwritten the default user table with an existing table.
When trying to register a new user i get the following error:
Argument 1 passed to Illuminate\Auth\SessionGuard::login() must be an instance of Illuminate\Contracts\Auth\Authenticatable, instance of App\customUser given, called in {path}\vendor\laravel\framework\src\Illuminate\Foundation\Auth\RegistersUsers.php on line 35
To overwrite the default users table with my own I have made the following changes:
///Auth.php///
//Auth defaults:
'defaults' => [
'guard' => 'web',
'passwords' => 'customusers',
],
//Auth guards:
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'customusers',
],
//User providers:
'providers' => [
'customusers' => [
'driver' => 'eloquent',
'model' => App\customUser::class,
],
I don't know if these changes could cause the error I'm facing.
The error is supposedly fired in this part of 'RegisterUsers.php'
$this->guard()->login($user);
This is part of the function 'register', which looks like this:
public function register(Request $request)
{
$this->validator($request->all())->validate();
event(new Registered($user = $this->create($request->all())));
$this->guard()->login($user);
return $this->registered($request, $user)
?: redirect($this->redirectPath());
}
Any help regarding this error would be kindly appreciated, I'm fairly new to Laravel so I would like to recieve a clear explanation to my problem so I can understand why it is calling this error.
Kind regards,

Answer 1

Your model needs to extend Illuminate\Foundation\Auth\User, otherwise you cannot use it with the authentication methods like login / logout etc.
In your customUser model add the following:
use Illuminate\Foundation\Auth\User as Authenticatable;
class customUser extends Authenticatable
I would also recommend to rename your class customUser to CustomUser in order to follow PSR-1:
Class names MUST be declared in StudlyCaps.
The term ‘StudlyCaps’ in PSR-1 MUST be interpreted as PascalCase where
the first letter of each word is capitalized including the very first
letter.

On RegisterUsers.php you need to include
use Illuminate\Foundation\Auth\AuthenticatesUsers;
and below class RegisterUsers extends Controller
you need to add
use AuthenticatesUsers;
