Tested Jenkins in prod and vs py3.12, this works.

So finally the fix is in the notebook and a ravenpy release was not required at all, since it works again in prod without new ravenpy?

I suppose not. We need a release anyway, but we can now wait a few weeks for the new features to get support. Glad things are working!
