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

[MarcSkovMadsen]

I'm trying to get leafmap working with Panel similarly to Solara-Leafmap.

A lot of features work. But when I click the tool icon nothing visible happens. But in the console the error below is logged.

Error: Could not process update msg for model id: d5ea3f69eff947928f88b58f36d3ceaa

import leafmap

import panel as pn

pn.extension("ipywidgets")

widget = leafmap.Map()

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

You can see how it should work here

I don't know if this issue is caused by ipywidgets_bokeh or by leafmap. Thus I have crossposted in ipywidgets_bokeh #106

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.

[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()
