I have some rules in my controller (I also tried using a form request and result is the same):
use App\User; ..... $rules = [ 'email' => 'required|email|unique:users', 'name' => 'required|min:8', 'password' => 'required' ];
The table users exist as well as the field email.
Name and password rules work fine. The email rule throws this error:
ReflectionException (-1) Class users does not exist
