Request is yielding forever

[jmkd3v]

httpx.AsyncClient.request is yielding forever. After debugging for 20 minutes and trying to find the function that was yielding, I've narrowed down the issue to this code in _client.py:

with request_context(request=request):
    (
        status_code,
        headers,
        stream,
        extensions,
    ) = await transport.handle_async_request(
        request.method.encode(),
        request.url.raw,
        headers=request.headers.raw,
        stream=request.stream,
        extensions={"timeout": timeout.as_dict()},
    )

I checked the source of handle_async_request and it is as follows:

raise NotImplementedError(
    "The 'handle_async_request' method must be implemented."
)  # pragma: nocover

This is incredibly frustrating as sometimes it just starts happening when I drop in another library (in this case, Flask 2 with async) and completely breaks our workflow.

Small update. This seems to only occur when I start the function with asyncio.create_task - just a plain old await works fine.

Moving over to Quart seems to fix this issue.

You'd need to give a clearer reproducible example in order for someone to be able to give you a hand with this.

I honestly have no idea why it does this, so it's hard for me to make a reproducible example.
