Как читать Volley Неожиданный код ответа 500

Question

Привет, ребята, я не знаю, как прочитать фактическое подробное сообщение об ошибке с сервера, все, что я получаю, это E/Volley: [73767] BasicNetwork.performRequest: Неожиданный код ответа 500 для https://xxxx.com/xxxxx Я видел людей, добавляющих слушателя onErrorResponse, но мой не работает, поэтому я явно что-то пропустил, ниже мой код, любая помощь приветствуется.

Answer 1

Я думаю, что там может быть ошибка в конструкторе GetUserFavoritesRequest в

super(Request.Method.POST, LOGIN_REQUEST_URL, listener, null); 

изменение нулевой до errorListener.
