Issue

Whenever I join my SMP server, it would disconnect and send a error message. It only happened whenever Fabric Tailor was installed.

To Reproduce

Steps to reproduce the behavior:

1. Install Fabric Tailor on client and server
2. Try to join

Logs

Log with other mods.

Are you using any other mods?

Tried with other mods, tried without other mods, same problem.

io.netty.handler.codec.EncoderException: Failed to encode packet 'clientbound/minecraft:custom_payload' (fabrictailor:hello)

I've seen this mentioned in discord. Please remove fabrictailor from your client atm

[snowzzrra]

sure, would it still work server only or would the error repeat itself?

[samolego]

Yeah, sever only works fine
