TypeError: Class constructor O cannot be invoked without 'new'

Hi,

I'm trying to run your jupyter notebook on my server, but I keep getting the following error:

Failed to create view for 'SmilesView' from module 'smiles_widget' with model 'DOMWidgetModel' from module '@jupyter-widgets/base'
TypeError: Class constructor O cannot be invoked without 'new'
    at new i (INTERNALSERVERADDRESS/nbextensions/jupyter-js-widgets/extension.js?v=20230322101509:2:257463)
    at INTERNALSERVERADDRESS/nbextensions/jupyter-js-widgets/extension.js?v=20230322101509:2:742192

I think this might come from version mismatch of our jupyter-widget?

IPython          : 8.6.0
ipykernel        : 6.18.0
ipywidgets       : 8.0.2
jupyter_client   : 7.4.7
jupyter_core     : 5.0.0
jupyter_server   : 1.23.2
jupyterlab       : 3.5.0
nbclient         : 0.7.0
nbconvert        : 7.2.5
nbformat         : 5.7.0
notebook         : 6.5.2
qtconsole        : not installed
traitlets        : 5.5.0```

Thanks for any insigths on this, and it would be very helpful if you published your widget with cookiecutter!

Best,

Hugo
