CFArgument заставляет функцию возвращать ОШИБКУ 415

Я пытаюсь создать веб-службу REST в CF11, и я получаю сообщение об ошибке, не совсем понимаю, откуда оно взялось.

Шаг 1
Я создал функцию, которая возвращает результаты запроса. Работает нормально
Шаг 2
Добавил несколько CFArguments и функция возвращает 415 Unsupported Media Type
Шаг 3
Удалил cfarguments и функция снова работает.....

Кто-нибудь с рекомендацией, пожалуйста?

Это компонент
