Ambiguous error when getting 401 from server

[vhaldemar]

Hey!
I'm trying to use a sse backend which could return 401 Unathorized with "application/json" in headers and getting very ambiguous exception without any leads.

  File "...", line 120, in _run_stream
    async for sse in event_source.aiter_sse():
  File ".../lib/python3.12/site-packages/httpx_sse/_api.py", line 39, in aiter_sse
    self._check_content_type()
  File ".../lib/python3.12/site-packages/httpx_sse/_api.py", line 19, in _check_content_type
    raise SSEError(
httpx_sse._exceptions.SSEError: Expected response header Content-Type to contain 'text/event-stream', got 'application/json'

I'm not sure how usual it for see backends and how to properly fix it;
response.raise_for_status() in EventStream constructor will probably do the trick

You can call

event_source.response.raise_for_status()

before you call aiter_sse to handle this case if I'm understanding correctly.
