Looks like someone has missed a potential error/null generator later in the code, as it’s asking a null for it’s Name property. Focus these days is on pyRevit5 so I doubt you’ll get bug fixes for 4.8.x builds.

It hurts my eyes and make them bleed when I look at this code that is old and dated when I think about my understanding of python in general…

This is happening because your file is not workshared, worksets aren’t activated.

I will try and fix that in wip installers

me from the future… :crazy_face:

I fixed that already, it is in the develop branch, meaning you can install WIP installers and get that change
