django fastapi asyncio Python

I'm working through a tutorial and I'm currently working on a FastAPI application that interfaces with a Django ORM for database operations. I have an endpoint that fetches user data asynchronously, and I'm working with a `RuntimeError: Task <Task pending name='Task-1' coro=<User.fetch() running at ...> cb=[<Future finished exception=RuntimeError('Task got canceled')>]> got canceled.` behavior when executing the query. Here’s a simplified version of my code: ```python from fastapi import FastAPI from asgiref.sync import sync_to_async from my_django_app.models import User app = FastAPI() @sync_to_async def fetch_user(user_id): return User.objects.get(id=user_id) @app.get('/users/{user_id}') async def get_user(user_id: int): user = await fetch_user(user_id) return user ``` I have tried to run this in different ways by wrapping the `User.objects.get()` call into a sync-to-async wrapper, but it seems that the database call gets canceled if it takes too long. I also ensured that my database connections are correctly configured for async use in FastAPI by using `DATABASE_URL` in my settings. I’m using Django 3.2 and FastAPI 0.68.0. Any insights on how to better manage this interaction or how to handle the async context would be greatly appreciated!
