Hello, This is my first post. Sorry if mistackes Using Revit 2023. pyRevit v4.8.16.24121 When I run preflight Checks, I got following Error [Screenshot_2] I have followed the recommendation shared here [Bug]: Add on Crashes on Revit startup …

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 Fix Model Checker Attribute Error · pyrevitlabs/pyRevit@d364f37 · GitHub

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
