StreamingHttpResponse being buffered when using uvicorn/gunicorn/daphne in Django

I have a very simple view that Streams a repsonse. When using python manage.py runserverthe stream works as expected. But, when we use uvicorn app.asgi:application or daphne app.asgi:application or gunicorn app.asgi:application the stream is buffered in the UI and the response arrives completed instead of by chunks.

    result = core_services.generate_ai_v3_response(
        prompt=prompt,
        previous_response_id=previous_response_id,
        broker_id=broker_id,
    )

    response = StreamingHttpResponse(result, content_type="text/event-stream")

    # Add proper streaming headers
    # Add aggressive streaming headers
    response["Cache-Control"] = "no-cache"
    response["X-Accel-Buffering"] = "no"

    return response
