ASP.NET Core — код состояния ответа не указывает на успех: 500 (внутренняя ошибка сервера) в HttpResponseMessage.EnsureS ⇐ C#

[Гость]

В веб-API ASP.NET Core я использую API С SOAP XML.
Я ожидал отправить запрос к API и получить ответ
Поначалу все работало, но вдруг появилась такая ошибка:

Код: Выделить всё

"System.Net.Http.HttpRequestException: Response status code does not indicate success: 500 (Internal Server Error).\r\n   at System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode()\r\n   at RequestHandler.SendSoapWebRequest(String url, String action, String xmlString) in C:\\WebRequestHandlers\\RequestHandler.cs:line 64\r\n   at Implementations.ChequeBooksServices.GetQueryChequeBookAsync(QueryChequeBookRequestDto chequeBookDto) in C:\\ChequeBooksServices.cs:line 135",
