TextTagger - Javascript Error

[PawaritL]

the TextTagger object seems to constantly generate a Javascript error in JupyterLab (I'm using 3.4.8) with the latest versions of ipywidgets (8.0.2) installed. I keep getting "Class null not found in module @jupyter-widgets/controls" (see second screenshot of Chrome developer console). Any ideas on what might be causing this? Normal text classification works fine. Many thanks!

Hi there, is this with the latest version of ipyannotations?

I haven't seen this before but the developer console output looks like there is a conflict between different dependencies. I'll take a look. Does the widget still work?

Many thanks for creating this amazing library btw!

This is with: ipyannotations==0.5.1 ipywidgets==8.0.2 jupyterlab==3.4.8 jupyterlab-widgets==3.0.3

The widget works for JupyterLab - tested with superintendent just now (see screenshot attached). It's just that this big javascript error block keeps popping up with every cell.

Thanks so much for your help!

FYI - for classic Jupyter notebook (not Jupyter Lab) the widget doesn't work at all, this is what happens:

I see you are using ipywidgets 8. Does it work with ipywidgets 7?

I tried just now with ipywidgets 7.6 and 7.7:

• for JupyterLab, we see a new Javascript error about Failed to load model class 'VBoxModel' from module '@jupyter-widgets/controls':

• for classic Jupyter notebooks, there's no clear error but the widget doesn't show:

Hi, and apologies for not getting back on this - I was on holiday.

I can reproduce your error in JupyterLab - I see the same large box with javascript errors. However, it does resolve for me when using ipywidgets 7.7.2 - jupyterlab no longer displays the error.

I can also reproduce the error in Jupyter Notebook - I find it a bit hard to understand the issue as the error refers to mime-type mismatches referring to base jupyter widgets, but when loading ipywidgets by itself it works and there is no error. I think this may be something to raise with the core jupyter widget devs. @jasongrout-db - do you have a suggestion for how to fix this or where to raise an issue?

For @PawaritL - if you install ipywidgets 7.7.2 does this also solve the issue for you? If so I may release a new version with the ipywidget version pinned.

Thanks again for raising this!
