JS error in JupyterLab

[jovenitti]

When trying to run the following code in a notebook

from ipyaladin import Aladin
aladin = Aladin()
aladin

I get the following error:

[Open Browser Console for more detailed log - Double click to close this message]
Failed to load model class 'AnyModel' from module 'anywidget'

From Jupyter Lab v3.5.2 (Jupyter Server 2.5.0).
anywidget version 0.9.2

Note that using VSCode (with the same jupyter kernel) it works.

Hi! 🙂

I think this was solved in anywidget here manzt/anywidget#553 . It didn't work with jupyterlab 3 before

So you have two solutions:

• either upgrade jupyterlab to version 4
• or upgrade anywidget to a version more recent than this commit (at least 0.9.10)

Hope this works
