Why doesn't it output the validator message for Rule::notIn?

Question

Laravel

rule

$rules = [
          'role' => [
            Rule::notIn([КОД])
          ]
      ];

Message

$messages = [
          'role.notIn' => 'Отказ',
      ];

Return
The selected role is invalid.
And I didn't write it.
