Bug Description

When I try to connect to my fabric 1.20.2 server through 1.20.1 client, I get this error in velocity console:

And even weirder error in the server console, that I showed above

Everything is fine if I try connectiong from 1.20.2 client, so it might be viafabric issue. However, it doesn't occur without fabric proxy lite, so I reported it to them as well

Steps to Reproduce

1) Install viafabric, viabackwards and fabric proxy lite on 1.20.2 server 2) connect the server to velocity 3) try to connect to it from 1.20.1 client or lower

Expected Behavior

Joining the server

Checklist

[ ] I have checked if this is specific to ViaFabric platform, and doesn't happen when running it on other platforms (Paper/Sponge/Velocity/Waterfall).
[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.
