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.
