Failed to convert command errors

Expected behavior

No spam in the logs 😅

Observed/Actual behavior

Since build 163 of paper 1.21.4 I've been spammed with logs that look like the following:

According to Lynx on Discord "We touched commands in 163 and apparently it blows up there somewhere o.O"

Steps/models to reproduce

This is a creative server where it happened. Pretty hard to tell how to reproduce this honestly because there are lots of weird things on this server which are somewhat out of my control.

I hope you're able to work with the error logs :/

Plugin and Datapack List

Hopefully not relevant/necessary
