Console Error

Bug Description

Using the viaproxy from 1.12 client to 1.20.5/.6, it only allows me to enter the lobby of the server, and when i try to enter gamemodes it gives me error. After a couple tries, i end up getting stuck in the ground.

Checklist

[X] Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. BungeeCord), 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 a build from https://ci.viaversion.com/ and the issue still persists.

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

The server is not 1.20.6, you need to select a (more) correct target version since the server is presumably already running ViaVersion. https://github.com/ViaVersion/ViaBackwards/pull/778 is going to fix that particular console error, but in order to not run into other issues, you need to change the target version

Thanks for helping me with this.

Ive tried all the other versions. Only 1.20.1 and 1.20.5/6 seem to be working.

1.20.5/6 is my desired goal to enter the gamemode.

After a couple disconnects, I was able to login to the gamemode, however I was stuck on the ground upon spawnning in.
