I can't get anything to display in JupyterLab. I have taken a straightforward example from the API reference. See the screenshot below. The code runs and there is an output box like there should be something visible but is not.

Hi, could you check your jupytercad version?

@martinRenou

Also I'm curious about the output of jupyter labextension list, if you can provide it :)

@AlexGriffiths526

I am using Jupytercad 0.2.3

JupyterLab v4.0.2
C:\Users\AG\AppData\Local\anaconda3\envs\Jupyter4\share\jupyter\labextensions
jupyterlab_pygments v0.2.2 enabled X (python, jupyterlab_pygments)
@jupyter/collaboration-extension v1.0.0 enabled ok (python, jupyter_collaboration)
@jupytercad/jupytercad-extension v0.2.3 enabled ok (python, jupytercad)

The following extensions are outdated:
jupyterlab_pygments
Consider running "jupyter labextension update --all" to check for updates.

Disabled extensions:
@jupyterlab/filebrowser-extension:defaultFileBrowser

I'm clueless here.

TypeError: No provider for: @jupyter/collaboration-extension:ICollaborativeDrive. would indicate that jupyter_collaboration is not properly installed, but it seems to be found by your jupyterlab installation.

Is this error jlab_core.f68a597bc4700114bad4.js?v=f68a597bc4700114bad4:1 Plugin 'jupytercad:fcplugin' failed to activate. (anonymous) @ jlab_core.f68a597bc4700114bad4.js?v=f68a597bc4700114bad4:1 the first one you see in the JavaScript console? If there are other error messages higher up in the logs that may help debug.

Just as a data point: I get the same symptoms here: firefox, ubuntu, fresh mamba environment containing jupyterlab, with pip installed jupytercad.

Could you tell us which jupyter_collaboration version you have installed?

Also can you try installing jupytercad from conda-forge?

I'm clueless here.

TypeError: No provider for: @jupyter/collaboration-extension:ICollaborativeDrive. would indicate that jupyter_collaboration is not properly installed, but it seems to be found by your jupyterlab installation.

Is this error jlab_core.f68a597bc4700114bad4.js?v=f68a597bc4700114bad4:1 Plugin 'jupytercad:fcplugin' failed to activate. (anonymous) @ jlab_core.f68a597bc4700114bad4.js?v=f68a597bc4700114bad4:1 the first one you see in the JavaScript console? If there are other error messages higher up in the logs that may help debug.

Hiya,
It was the first error yes. But I have it filtered to only show warnings and errors.

I have opened up the JS console again today but strangely I have slightly different errors but still have the same issue. See log below.
