The bug

Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IllegalArgumentException: Cannot get ID for packet class net.md_5.bungee.protocol.packet.LoginSuccess in phase GAME with direction TO CLIENT @ io.netty.handler.codec.MessageToByteEncoder:125

Log output (links)

No response

Checking

• I am using BungeeCord and not a fork. Issues with forks should not be reported here.
• I think this is not an issue with a bungeecord plugin.
• I have not read these checkboxes and therefore I just ticked them all.
• This is not a question or plugin creation help request.

Are you using ViaVersion?

if you have viaversion, use it only in the backend servers and not in the bungeecord server
