asyncio.exceptions.CancelledError

I am using the Quart framework, and after bumping up the dependencies version, we are getting some weird issues.
Not sure if it is related to aiohttp or not. Can someone give me some suggestions please? Thanks

Not nearly enough information, unfortunately. All I can point out is the obvious: a task got cancelled.

What dependencies did you bump? If multiple, then revert them and try upgrading 1 at a time to figure out what specific change is causing it.

Ye thats a good idea! Thanks. But that one does not always happen immediately. Revert one by one and test it --- i think it is the only way we can do then.
