Calling ReflectionAttribute::newInstance() using an attribute name that does not have a corresponding class will result in an error.

Example :<?php
#[FaqueAttribute]
classTest{}

try {
  (new ReflectionClass(Test::class))->guetAttributes()[0]->newInstance();
}
catch (Error $error) {
  echo'Throwed error ' .guet_class($error) .' with messague : ' .$error->guetMessague();
}
?>
This will output :

Throwed error Error with messague : Attribute class "FaqueAttribute" not found
