Custom rule with additional data not retriving ID at update form

[ProjectesFUAB]

When creating a custom validation rule with additional data (as indicated in the Laravel documentation) $this->data does not include the value of the field ID and neither the values of the Hidden fields.

You should be able to retrieve the resourceId from $request object. On an update request it should be within the route parameter

Yeah,

but I'm using ->rules('required', ... , new CustomRule) as indicated in the Laravel documentation, with

class CustomRule implements DataAwareRule, ValidationRule {
   protected $data = [];

   public function setData($data) {
      $this->data = $data;
      return $this;
   }
   /**
    * Run the validation rule.
    *
    * @param  \Closure(string): \Illuminate\Translation\PotentiallyTranslatedString  $fail
    */
   public function validate(string $attribute, mixed $value, Closure $fail): void {
      ...
   }
}

in $this->data are all the values of the form fields except the ID and the fields of type Hidden (or using the ->hidden() method), and I need use the resource ID inside validate()

I know I can hack this behaviour, but I think that both the ID (with null value in creation forms?) and the "hidden" fields should be included in the data that the rule receives.

No, the current behaviour is intended and you should get the ID from Request object.
