some mod elements cause compilation errors

hi, i'm trying to create a living entity, but her procedure has a red block in the icon, and keeps saying that some elements of the mod cause compilation errors. Can someone help me? I've tried all the methods on the help page and the others I found on the internet and none of them worked.

my console output:
