Unknown Kaleido Exception!

[FishSlice75]

One of my scripts, which was generating PNGs from 685 Plotly Figures using 30 cores just errored with the following:

Cleaning tasks after error.
Traceback (most recent call last):
File "e:\.....virtualenv\Lib\site-packages\kaleido\kaleido.py", line 600, in write_fig_from_object
await _loop(args)
File "e:\.....virtualenv\Lib\site-packages\kaleido\kaleido.py", line 564, in _loop
args.pop("fig"),
^^^^^^^^^^^^^^^
KeyError: 'fig'
***************************** Unknown Kaleido Exception
'fig'

I have zero idea how to reproduce - is there anything extra I can add here to assist with the issue.
I will keep running it to see if I can reproduce, but this was in production (not seen it before).

Plotly : 6.5.0
Kaleido : 1.2.0

Thanks, I'll look for a smell in the code, if you can give mere context if would help
