Console Error when killing a mob

[Drizzt11]

No code or error pops up when the server is started but when there is a kill from a player I get this code in the console... I dont know what to make of it. I have installed the latest passing build of both mobhunting and customitemslib.

Server Info
Spigot - 1.20.2 - BUILD 3945

Plugins(And Version)

• Mobhunting 8.5.5-SNAPSHOT
• CustomItemsLib-1.0.9 - SNAPSHOT

Console Error Code
