Server crash if running Python 3.10 w/ Sanic 20.12

!!! ONLY APPLIES TO VERSIONS PRIOR TO Sanic v20.12 WHEN USING Python 3.10 !!!

Sanic v20.12 officially supports Python versions 3.6, 3.7, 3.8, and 3.9. However, if you accidentally run it with version 3.10 (which is not supported by Sanic 20.12), your server is prone to crashing on an incoming web request.

Impact

Anyone running Sanic server between 0.1.7 and 20.12 using Python 3.10.

Patches

Sanic v20.12.6

Workarounds

Use a supported version of Python (v3.6 - v3.9)

References

In asyncio, the explicit passing of a loop argument has been deprecated and will be removed in version 3.10 for the following: ... asyncio.Event
