Likely Javascript Error

I also have a daily GHA failing this AM, due to picking up Kaleido 0.4.1. I've "fixed" it by pinning to 0.2.1.

File /opt/hostedtoolcache/Python/3.11.8/x64/lib/python3.11/site-packages/plotly/basedatatypes.py:3835, in BaseFigure.write_image(self, *args, **kwargs)

    295         # Now we can use `write_bytes()`.
--> 296         path.write_bytes(img_data)

TypeError: memoryview: a bytes-like object is required, not 'NoneType'

Apologies if this should be its own issue, the error msg looks slightly similar to the last one above (something is None where it shouldn't be).

Hi @ryan-williams, sorry for your error.

The other issue is likely a matter of installing or running chrome/chromium (we no longer include it by default- its huge and updates too frequently), but I think your error may be different.

If you'd like me to help you debug it and/or send a fix to Kaleido, please set env var KALEIDO_DEBUG=true and run it again- although looking at your GHA, it may very well be that you need to add a line about installing chrome/ium.

I'm not 100% sure what the best way to install chrome is through GHA- we're doing it through snap (apt install) but there may be a faster method by curling from a google server.
