403 Errors

Hi! I'm currently working on a dasboard for a project and encountered the following error when using voila wit flex template:

[Voila] Kernel started: 95b91435-b44b-448e-b0ff-fd14d8ed667f

I think it has to do with voila not having access to the Ipywidgets; however, dropdown widgets work correctly on jupyter and the vanilla version of voila. I would appreciate if someone could guide me through a possible solution.

Did you ever figure this out?

Same issue with the latest current versions from pip (albeit with a hybrid pip/conda-forge environment), and jupyter-flex example notebooks.

voila                     0.5.6
jupyter-flex              0.9.1
ipywidgets                8.0.4  

As pointed in issue #172, even if allowing .js or all files e.g.:

cd ~/src/jupyter-flex/examples/widgets
voila \
    --template=flex \
    --VoilaConfiguration.file_allowlist "['.*voila\\.js']" \
    mpl-histogram.ipynb

then we get 404 on js files.

404 GET /voila/files/6060.voila.js (127.0.0.1) 0.40ms
404 GET /voila/files/6944.voila.js (127.0.0.1) 0.52ms
404 GET /voila/files/2412.voila.js (127.0.0.1) 0.40ms
etc.
