Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods Editor Tutorials: 1 - Minimal mod template

I tried out following this tutorial for my existing project that is only a level with just a few globals for scripts. I followed the tutorial and when I hit the generate definitions and build, I get the error:

Line
7029

Message
Auto-define Osiris query "WarningDialog"(): failed: type of parameter 2 unknown

Script File
_Attitude

Does anyone here know how to fix this?
