Upgrade kaleido 0.2.1 -> 0.4.1 is causing errors in CI

[bmosley]

Hi, first of all, thank you for this project. Really appreciate the work! After as of the 0.4.1 release several of our unit tests started failing here. In the meantime I've pinned our version to 0.2.1 and all is well but not sure if there's something deprecated that I didn't see before as our code hasn't changed in ages. Let me know if there's more information you need. Thank you.

         self._plotlyfier = os.path.join(
         os.path.dirname(os.path.dirname(os.path.abspath(__file__))),
         'vendor',
         'kaleido_scopes.js'
         )
         path = os.environ.get("BROWSER_PATH", which_browser())
         if tmp_path:
         temp_args = dict(dir=self.tmp_path)
         >       elif "snap" in path:
         E       TypeError: argument of type 'NoneType' is not iterable
         
         /usr/local/bin/python-3.12.0-1/lib/python3.12/site-packages/kaleido/scopes/plotly.py:64: TypeError

and also seeing this traceback as well with the only change being Kaleido 0.4.1

        # force a single process to manage the trace rendering
>       pio.kaleido.scope.chromium_args += (
            "--single-process",
            "--disable-gpu",
        )
E       AttributeError: 'PlotlyScope' object has no attribute 'chromium_args'

This might be the same as #223 but im not entirely sure

I have also just bit bitten by this issue.

A possible solution is to change the following line

Kaleido/src/py/kaleido/scopes/plotly.py

Line 64 in 2459633

elif "snap" in path:

to:

-elif "snap" in path:
+elif path is not None and "snap" in path:

Opened a PR just in case you think this is a viable solution: #227

Had the same issue today and 0.2.1 saved me in jupyterlabs, you beat me by an hour or so :) I can now write images again, I was confused as it worked fine two days ago and figured it was something to with how I original installed things the first time.

+1 to fixing this issue.

+1 to fixing this issue - downgrading to 0.2.1 did NOT work within Azure Databricks

• DBR: 12.2 LTS, 13.3LTS, 14.3LTS, 15.4LTS

After several hours of trying different DBR configs/Plotly versions/Kaleido versions, I've finally gotten it to work on
DBR: 15.4LTS
Plotly 5.1.0
