django async views queryset Python

I'm sure I'm missing something obvious here, but I've encountered a strange issue with I'm working on a project and hit a roadblock. I've been struggling with this for a few days now and could really use some help. I'm currently working with Django 4.1 and trying to implement async views to improve my application's performance. However, I'm running into a question where my async view returns an empty queryset despite the expected data being present in the database. Here's a simplified version of my async view: ```python from django.http import JsonResponse from django.views import View from .models import MyModel from asgiref.sync import sync_to_async class MyAsyncView(View): async def get(self, request): queryset = await sync_to_async(MyModel.objects.all)() data = list(queryset.values('id', 'name')) return JsonResponse(data, safe=False) ``` When I call this API endpoint, I see an empty list in the response: ```json [] ``` To troubleshoot, I added a synchronous view for comparison: ```python class MySyncView(View): def get(self, request): queryset = MyModel.objects.all() data = list(queryset.values('id', 'name')) return JsonResponse(data, safe=False) ``` This synchronous view works perfectly, returning the expected data. I’ve tried using `await sync_to_async()` in various configurations, but the results remain the same. I also ensured that the database is not being modified during the async call, which could lead to an empty result set. Could the scenario be related to how Django handles database connections in async views? Is there something I might be missing in my setup? Any insights or suggestions would be appreciated! I'm working on a CLI tool that needs to handle this. My development environment is macOS. I'd really appreciate any guidance on this. Any advice would be much appreciated. I'm developing on CentOS with Python. What would be the recommended way to handle this?
