Проблема проверки атрибута Akeneo

Question

У меня действительно простой вопрос. Поэтому я хочу вставить что-то еще в проверку атрибутов.

Я перешел по этой ссылке и вставил весь этот файл в свой комплект. https://docs.akeneo.com/cookbook/validation/customize_validation.html с некоторыми изменениями в файле.

Но это не работает. Что я здесь не так делаю? Возможно, это что-то действительно простое, но я не могу его найти.
