Expected behaviour

I'm trying to wrap a pydeck object in a Panel pane and display it in a Jupyter interactive window. A few months ago this was working.

Actual behaviour

When I create a pydeck, I'm seeing the following error:

09:59:37.281 [error] Widget load failure {} [ 'jsdelivr.com', 'unpkg.com' ] {
  className: 'JupyterTransportModel',
  moduleName: '@deck.gl/jupyter-widget',
  moduleVersion: '~8.8.*',
  isOnline: true,
  timedout: false,
  error: '{}'
}

Next everything seems to be working (I can see and interact with the pydeck), but when I try to wrap the pydeck object in a Panel pane the interactive Jupyter window doesn't show/load anything.

Steps to reproduce:

import panel as pn
import pydeck

print(f"pydeck: {pydeck.__version__}")
print(f"panel: {pn.__version__}")

pn.extension("deckgl")

if __name__ == "__main__":

    deck = pydeck.Deck(
                        map_style = "light",
                        tooltip = False,
                    )

    x = pn.pane.DeckGL(deck)

So deck does show up, but x doesn't work.

Does this work for you in Jupyter Lab,
I'm unable to get this working in Jupyter lab, basically getting the exact same result.

Thanks @DonJayamanne

I just ran it in a Jupyter Lab and indeed here both deck and x show the output correctly (and nearly identical).

In VSCode, the output box for x does have the correct height, but it doesn't show any map.

[DonJayamanne]

Please can you provide the list of packages and versions required to setup a conda env to get this working in Jupyter lab
Please include all steps when using a vanilla setup (i found some additional steps online for panel when using Jupyter lab, not site what’s required and what isn’t)
Optionally you can share a cons env yml file

Using that I can test Jupyter lab locally and figure out what’s required in vscode

[bertcoerver]

Not sure if this is what you mean, because it is working in Jupyter Lab (i.e. its not reproducing the error), but here is the yml file for the environment that has the error in VSCode.
