Conflict with mod "Supplementaries"

when trying to use a jar from that mod on a slime it returns a null bucket crashing the game
(the slime is supposed to get trapped in the jar)

"java.lang.NullPointerException: Bucketable modded entity minecraft:slime returned a null bucket!"

I saw a bunch of reports related to the edelwood bucket, not sure if this is already known or not, it's my first time reporting an issue here.

This should no longer happen in 1.21.
