Django async view not returning JSON response when using Django 4.1 and asyncio

django asyncio asynchronous Python

I'm working on a project and hit a roadblock. I'm collaborating on a project where This might be a silly question, but I'm currently developing a Django application using version 4.1 and trying to implement an asynchronous view to handle some heavy data processing using the `asyncio` library... However, Iโ€™m working with an scenario where the view does not return a JSON response as expected. Instead, I get an empty response with a status code of 200. Hereโ€™s the code for my view: ```python from django.http import JsonResponse from django.views import View import asyncio class MyAsyncView(View): async def get(self, request): await asyncio.sleep(1) # Simulating a long-running operation data = {'message': 'Hello, async world!'} return JsonResponse(data) ``` Iโ€™ve also added this view to my `urls.py`: ```python from django.urls import path from .views import MyAsyncView urlpatterns = [ path('async/', MyAsyncView.as_view(), name='my_async_view'), ] ``` When I navigate to `/async/`, I see a response with a 200 status, but the body is empty. Iโ€™ve checked that my Django settings have `ASGI_APPLICATION = 'myproject.asgi.application'` set up correctly, and Iโ€™m running the server with `daphne` instead of `runserver` to handle ASGI. I also tried using `JsonResponse` directly with synchronous code to confirm that the view works on a basic level, and it does return the expected JSON. Is there something specific Iโ€™m missing in terms of configuration for Django to support async views, or do I need to handle the response differently? Any help would be greatly appreciated! My development environment is Ubuntu. What's the best practice here? This is my first time working with Python 3.11. I'm using Python 3.9 in this project. Any help would be greatly appreciated!
