Description of expected behavior and the observed behavior

Complete, minimal, self-contained example code that reproduces the issue

FastAPI tutorial pages do not render anything to page until pip install wsproto.

pip install bokeh might also be required... I assume not, but I don't use python enough to test it.

I found the fix here, and it worked for me:

I made a mistake - the tutorial works, but a custom pn.Column and pn.Row do not render, and show a type error in the linter. (Well, the sliders app didn't work for me, but I could have made a mistake.)
