Hello people

I got the error message “warning:IronPythonEvaluator.EvaluateIronPythonScript operation failed” from a script in my dynamo.

Here the image of the dynamo :

The script retrieve all elements from groups in my project

The script is circled in red and came from the Clockwork package.

I’ve just extracted the script so I can share my script and my friends doesn’t have to download the package

The script is working in my computer but not in my friend’s computer, we got the same version 2.0.3 on Revit 2019 and he got this error message only

Does anyone got an idea ?

Hello I ask again for help do someone got an answer ?
