Complete novice here trying to make my first plugin for pyRevit. I have little to no coding knowlege so I used chatGPT to write this code but I can’t seem to get past the following error:

I am trying to create a plugin that will match all the leader lines of a tag to the same angle.
I have no idea what I am doing so any help would be appreciated.
no use.
on forum and won’t get the expected result if you don’t know a bit of the ins and outs of the Revit API or pyRevit
!
