What happened?

when I set a custom rule for a field with asterisk and I set it's custom error message too. if the field is error it will show Validation.mycustom_rule instead the custom error message

Steps to Reproduce

• my custom rule

  public function mycustom_rule(string $value): bool
  {
    $theModel = new App\Models\TheModel();
    if (empty($theModel->getData($value))) {
        return true;
    }
    return false;
  }
  //make sure this rule return false so it can produce the error

• my validation rules

  $validationRules = [
  'test_data.*'  => [
      'label' => 'test_data',
      'rules' => 'required|mycustom_rule',
      'errors' => [
          'required' => '{field} is needed',
          'mycustom_rule' => '{field} of {value} is not exist',
      ],
  ],
  ];

• tested data

  $data= [
  "test_data"=>["test1","test2"],
  ];

• run validation and get the error

  $validation = \Config\Services::validation();
  $validation->setRules($validationRules );
  $validation->run($data);
  $errors = $validation->getErrors();

• error messages that I got kinda like this (my actual error is in json) the error messages that I got are more like when I didn't set any error message for my custom rule

  Array
  (
  [test_data.0] => "Validation.mycustom_rule",
  [test_data.1] => "Validation.mycustom_rule"
  )

Expected Output

Array
(
    [test_data.0] => "test_data of test1 is not exist",
    [test_data.1] => "test_data of test2 is not exist"
)

Anything else?

ps : please forgive and correct me back if there are some mistyping because the actual codes and data is kinda secret
