Hi, and welcome,
Have a look at QuickStart in the Realm of pyRevit and the Revit API
Please do post the error window image.
The important part tells us which lines and methods are throwing the error.
You also need to give us a way to reproduce the issue. Either a step by step description, a revit file or both.
That being said, pyTiba is maintained by tillbaum (Tillmann Baumeister) · GitHub
You should open an issue
