console error with CMI (maybe plugin conflict)

[Lia-LV]

Describe the bug
Console error when I open coin trade(anvil inventory)
( with Purpur 1.20.6, CMI 9.7.3.1, TradeSystem 2.5.3 Hotfix-4 )

To Reproduce
Steps to reproduce the behavior:

1. Open Trade with players
2. Open Coin Trade(anvil inventory)
3. See console error

Expected behavior
It doesn't affect for users as far as I think, but console gets dirty.
