Panel Leafmap: Error: Could not process update msg for model id about leafmap

[giswqs]

This does not seem to be issue unique to leafmap. I tried ipyleaflet, it does not work either.

import ipyleaflet

import panel as pn

pn.extension("ipywidgets")

widget = ipyleaflet.Map()

layout = pn.Column(
    widget,
).servable()

This seems an issue with ipywidgets_bokeh. Can you try using ipywidgets_bokeh directly with Panel without leafmap? If it doesn't work either, then it is an ipywidgets_bokeh issue. Otherwise, it may be a leafmap issue.
