How do versions after py3.10 implement asyncio.get_event_loop with the same behavior as previous versions

Question

python3.10-asyncio-get_event_loop

Deprecated since version 3.10: Emits a deprecation warning if there is no running event loop. In future Python releases, this function may become an alias of get_running_loop() and will accordingly raise a RuntimeError if there is no running event loop.

The behavior of get_event_loop has changed in version 3.10, now the sanic-jwt library needs to be compatible with later versions of 3.10, and needs to be modified to remove this warning(DeprecationWarning: There is no current event loop)

The place of the warning is the call method under ConfigItem on line 134 sanic_jwt/configuration.py

I tried the method of this article and the test did not pass. It should not match the behavior of the version before 3.10

If you want to patch the library, you could replace line 134:

if asyncio.get_event_loop().is_running():
    # some code

with:

try:
    asyncio.get_running_loop()
except RuntimeError:
    pass
else:
    # some code

That should work with all versions of Python.
