To Reproduce:

• Install ProtocolLib version v4.7.0
• Install VentureChat 3.6.0
• Start and join the server as a new player

Expected behavior: I expect this error not to occour.

Thanks for your help!

FYI: ProtocolLib dev said it's this issue is related to VentureChat itself: https://github.com/dmulloy2/ProtocolLib/issues/2624

What is the server version? Not enough info here to reproduce.

This server is running Paper version git-Paper-84 (MC: 1.17.1) (Implementing API version 1.17.1-R0.1-SNAPSHOT) (Git: 5059ada) | @Aust1n46

https://api.papermc.io/v2/projects/paper/versions/1.17.1/builds/84/downloads/paper-1.17.1-84.jar

This is what you're using? If so, why are you using such an out of date build?

Works fine for me on the latest paper for 1.17.1: https://api.papermc.io/v2/projects/paper/versions/1.17.1/builds/411/downloads/paper-1.17.1-411.jar

Don't have the time right now to downgrade my jdk to be able to run build 84...

I'm also using ProtocolLib 5.11. Some random snapshot v669. Never had any issues with ProtocolLib as long as I was using a supported version for my server version.

Worked with the latest Paper version!
