Cannot call raise_for_status as the request instance has not been set on this response.

[DeoLeung]

if upstream failed with 599, calling raise_for_status raises RuntimeError, is it a bug?

[tomchristie]

Could you include a runnable example to demonstrate?

[DeoLeung]

argh, I made a pytest and it's passing :)

should be something wrong with my subclass client, I will double check it

[DeoLeung]

the problem was, I did some other error handling logic in a subclass client, which return a new httpx.Response

def handle_error(res: httpx.Response):
  return httpx.Response(...)

now doing below works

def handle_error(res: httpx.Response):
  return httpx.Response(..., request=res.request)
