Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods Beginner with the Toolkit request some help

I try to fix my problem, but it's complicated. I try to "build" and without any Script I have this bug. The consequences are that I can't do any script if don't find the problem.

Someone can help me ?

Maybe a "?" somewhere block the "build" ... on line 643... but where is these line...
