Для решения этой задачи, вероятно, намного проще использовать `body` в пользовательском обработчике `RequestValidationError` ([Обработка ошибок](../tutorial/handling-errors.md#use-the-requestvalidationerror-body){.internal-link target=_blank}).

Но этот пример всё равно актуален и показывает, как взаимодействовать с внутренними компонентами.

///
