Error in customizing the default user registration Laravel Auth

Question

Error after registering and redirecting

PS: he makes the registration normally, and I can access normally, but always give this error!

I made a modification only in the user register, I parameterized my relationship many to many that also works

 public function register(Request $request)
{

    $this->validator($request->all())->validate();

    event(new Registered(
        $user = $this->create($request->all())->companies()->attach($request->company_id)


    ));

    $this->guard()->login($user);

    return $this->registered($request, $user)
                    ?: redirect($this->redirectPath());
}

THE ERROR IS IN THIS CODE SNIPPET $this->Guard()->login($user); ** **I BELIEVE ->attach($request->company_id) is making the user give a different return than $this->Guard()->login($user); needs

Answer 1

The function attach is returning null for the variable user.

In his job login the expected parameter shall implement the interface Authenticable which is common in the class User, to solve this create a variable with the user and do the attach without using the chained methods, see:

$user = $this->create($request->all());
$user->companies()->attach($request->company_id);

...

$this->guard()->login($user);

IT WORKED OUT THANK YOU MT

$user = $this->create($request->all());
    $user->roles()->attach(12);
    $user->companies()->attach($request->company_id);

    event(new Registered($user));

A doubt!! I’m using Laravel Defender but the $user->attachRole() Object Error function
