Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IllegalArgumentException: -1

[Type-32]

has anyone encountered an issue where they have the same mod installed on client and server but when the client tries to join the server the client disconnects immediately and gives this `Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IllegalArgumentException: -1` while the problem exists only when the mod is loaded?

Repo: https://github.com/Type-32/PreciseManufacturing/tree/1.20.1

Forge 1.20.1 Mod, logs gives no useful info, but I'm still gonna put it here

Server logs: https://pastebin.com/SUBbg0fF

No client logs here because when client disconnects it only shows that is has disconnected, and nothing more
