Does the Param Rest Provider still work?

I am trying to add a rest-api to my panel application, and looking at the
“–rest-provider param” option
However I can not get it to work, I was trying implement the example here:
https://blog.holoviz.org/panel_0.10.0.html#REST-APIs
But no dice.

I did get the “rest-provider tranquilizer” to work; but only if I downgraded to python 3.8.

Does anybody happen to use the “rest-provider param” and could provide a minimal working example or guidance?

Thank you

I can’t get it to work either.

There seems to be an error in the URL anyway, I suppose it should read http://localhost:5006/rest/slider.

If you don’t get an answer, maybe you could file an issue on GitHub? Also mentioning tranquilizer, since I don’t think it’s intended to work only with Python 3.8.
