Bug Description

When viaversion has loaded and started injecting i got this error.

Steps to Reproduce

1. Just start server.

Expected Behavior

I expected normal work of plugin. I installed snapshot build because viaversion 5.0.3 randomly disconnects me with error.

Additional Server Info

I have a velocity on which i did't installed viaversion.

Checklist

• [X] Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. Velocity), not on both.
• [X] I have included a ViaVersion dump.
• [X] If applicable, I have included a paste (not a screenshot) of the error.
• [X] I have tried the latest build(s) from https://ci.viaversion.com/ and the issue still persists.

[Barvalg]

Please update all Via* plugins from https://ci.viaversion.com/.In case the issue still persists send the new dump and the issue will be reopened
