# What does this PR do? As per docs [1], since python 3.11 wait_for() raises TimeoutError. Since we currently support python 3.10+, we have to catch both. [1]: https://docs.python.org/3.12/library/asyncio-task.html#asyncio.wait_for [//]: # (If resolving an issue, uncomment and update the line below) [//]: # (Closes #[issue-number]) ## Test Plan No explicit testing; just code hardening to reflect docs. [//]: # (## Documentation) Signed-off-by: Ihar Hrachyshka <ihar.hrachyshka@gmail.com>
