Hi @eirannejad and @Alain , Continuing this topic , I’ve noticed that the new script editor throws some rather verbose error messages, compared to the GhPython component. The new IronPython component is especially detailed in the traceback. I’m not really sure if all that extra information is useful: …

Agreed and thanks for starting this thread. I made the YT below to clean this up: RH-86121 Cleanup python traceback messages

This is much less intense, but I wonder if the rhinocode file GUID parts of the error message is actually useful? [2026-04-29 100048-Grasshopper - unnamed] Also, IronPython seems to have lost the inline error message (edit: not for all errors though).
