Extension name (the extension in question)

webpubsub

Description of issue (in as much detail as possible)

appears this just needs an upgrade

I was able to work around by running (I'm in azure cloud shell):

/opt/az/bin/python3.10 -m pip install websockets --upgrade --target ~/.azure/cliextensions/webpubsub/
