Я использую MultipartRequest Volley Post запрос на отправку, я получаю ошибку сервера

BasicNetwork.performRequest: неожиданный код ответа 500

Сервер принимает запрос Postman без проблем.

Кроме того, я http://httpbin.org/post проверял, прикреплены ли изображение и параметры, и мне кажется, что все в порядке. Кто-нибудь может мне помочь с этим. Пробовал искать часами, но так и не смог решить эту проблему.
