We have Python app engine backend. It was correctly responding except last 3 hours. C# Client is getting error when trying to parse response callback from POST request.

C# code to end getting response:
WebResponse wr = _webRequest.EndGetResponse(ar).
Exception says "Message: System.Net.WebException: MonoPosixHelper ---> System.DllNotFoundException: MonoPosixHelper".

It is strange because only from google appengine we can't get response to POST request in C# code. Response is ok when we're trying to use Chrome Postman or even raw python requests.

Please, ask for details.

Best regards,
Peter

Hello. Thanks for posting to the community here.

In order to help here, I would need some more information, assuming you're still experiencing this issue:
  • The error mentioned may have a few different causes. Can you provide the full stack trace?
  • Can you provide the request and response headers for both your C# client test and Postman test?
  • Is your Python application serving response over HTTP/HTTPS? Are you compressing the responses?
  • On what OS is your C# client being developed and run?
With the above information, I may be better equipped to help you find a solution.

Hi. I'm sorry to answer only now. The problem was solved and it was on client side. Thank you for your time!
