Minecraft Version

1.20.x

Mod Loader Version

Mod Version

1.3.4-1

Describe the Issue

Mod fails to load, we see errors in the log. I have tried with Java 1.17 and 1.20 no change in behavior.

This is where I think the issue is but do not know how to fix.

Do you use any other mods except the required ones?

Yes but they are new.

Did try fresh serve with just Dehydration and required addons. No change

Fixed with 88e6748
