Describe the bug
I downloaded the datapack but it doesn't work

Datapack/Mod Version
e.g: v1.0 and 1.1

latest.log
log file

Oh man, those versions are VERY old and very unsupported, a lot of the newer items added by later versions just aren't in there

Check your advancements, in the Jake's Build Tools tab. You'll see what items you have access to in your version

I may go back and update these older versions with the new items, but 1.20.4 is OLD, and I think support for 1.21.1 would come first

thanks for the answer
