Did you find any solution? I am also stuck at this problem.

Instead use this:


> jupyter server extension enable --py jupyter_http_over_ws

This worked for me

You note here this gives a warning about being deprecated and so it may not be a viable solution going forward unless something changes about the deprecation plans.

I have this issue as well. Commenting here so I will get notified in case someone comes up with more information.
