* **Валидации** ответа.
  * Если данные невалидны (например, отсутствует одно из полей), это означает, что код *вашего* приложения работает некорректно и функция возвращает не то, что вы ожидаете. В таком случае приложение вернет server error вместо того, чтобы отправить неправильные данные. Таким образом, вы и ваши пользователи можете быть уверены, что получите корректные данные в том виде, в котором они ожидаются.
