The view didn't return an HttpResponse object. It returned an unawaited coroutine instead. You may need to add an 'await' into your view

Python: 3.8 Django: 3.2.

I am building a django app following this article(ERROR: Your view return an HttpResponse object. It returned an unawaited coroutine instead. You may need to add an 'await' into your view)

Here is my code:

import asyncio

This is the view

async def get_smokables():
    print("Getting smokeables...")
    await asyncio.sleep(2)

async def save_setting(request):
   await asyncio.gather(*[get_smokables()])
   return HttpResponse('ok')

Run command:

uvicorn config.asgi:application --reload

When I tried above code, it says "The view views.save_setting didn't return an HttpResponse object. It returned an unawaited coroutine instead. You may need to add an 'await' into your view."
