Handling request.json() Without Async in Starlette

[YuriFeigin]

Hi everyone,

I encountered an interesting challenge while working with Starlette. I have a def function (not async) that handles HTTP POST requests. However, I need to extract JSON data from the request body using request.json(). Since I can't use await in a regular def function, I tried using asyncio.run(request.json()), but it occasionally throws exceptions like:
RuntimeError: Task <Task pending name=‘Task-1639’ coro=<Request.json() running at lib/python3.9/site-packages/starlette/requests.py:249> cb=[_run_until_complete_cb() at lib/python3.9/asyncio/base_events.py:184]> got Future <Future pending> attached to a different loop

What would be the correct approach to handle request.json() without using async? I'd appreciate any insights or alternative solutions.

Thanks in advance!

You need to use async. Run the rest in a thread executor.
