Python-plugin example issue

[robostoneDK]

Hi
Is there a practical reason why the python-plugin example does not work?
This issue has been raised a couple of times since 2020 (#143 and #157), and the exact same issue exists today.
Just wondering if it is a dead-end, or if it actually works with a little tweaking?

This is the error that I get:
