Model file Customer.php

use Illuminate\Database\Eloquent\Model;

Answer 1

You have a mistake in validation, instead of:

request()->validate([
            'firstname' => 'required',
            'lastname' => 'required',
        ]);

You need use:

$this->validate($request, [
    'firstname' => 'required',
    'lastname' => 'required',
]);

There are other ways to validate which you can read about in official documentation Validation.
