Solving Errors Upgrading Existing Community Script (Auto Elevations for Rooms)

Belinda made a script and I’m trying to update it for Revit 2022/Dynamo 2.10, but encountering some errors. See this link here for her script and this video explanation.

I changed the “Pick Model Elements” from Rhythm to a python script recommended here. That worked.

Now I’m stuck at the “Plane.XAxis” not knowing how to recieve the CoordinateSytem parameter in the second grouping.

Anyone willing to take a bite out of this?
