Bug description

Whenever loading up my Paper 1.19.1-91 I get an error when the Server has successfully loaded up, the error appears to be harmless but it is weird nonetheless.

Steps to reproduce

1. Update to Essentials 2.19.5-dev+32-908189a.
2. Update to Paper 1.19.1-91
3. Load up the Server
4. When the Server has successfully loaded up you will see the error.

Expected behaviour

No error

Actual behaviour

Nothing but a harmless console error upon launch
