Django: guide with Async Views Returning None Instead of JSON Response

I'm working on a Django 4.2 application where I need to implement an async view that returns JSON data. However, the view keeps returning `None` instead of the expected JSON response. I've set it up using Django's async capabilities, but despite following the documentation, it seems like I'm missing something. My view looks like this: ```python from django.http import JsonResponse from django.views import View class MyAsyncView(View): async def get(self, request): data = await self.fetch_data() return JsonResponse(data) async def fetch_data(self): # Simulating an async call return {'key': 'value'} ``` When I try to access this view, I expect to see `{'key': 'value'}` in the response, but I get an empty response with status code 200 instead. I've also checked if Django is correctly set up to handle async views, and I’m running on ASGI with Daphne as the server. I've tried adding print statements inside both the `get` method and `fetch_data` method to ensure that the code is executing, and everything seems fine there. The async view works fine in standalone testing, but when I access it via my frontend, I get a response body of `None`. Additionally, I checked the middleware settings and confirmed that none of them are interfering with the response. Does anyone have any insight into why this might be happening or if there's something specific I should be checking in a Django async context? Any help would be appreciated!
