Issue with Industrial Craft 2 on Minecraft 1.19.2 Fabric Server - Unable to Join Server

[EvanYuan516]

Hello,

I am experiencing an issue with the Industrial Craft 2 mod (version industrialcraft-2-2.9.32+ex119-1.19.2-fabric) on a Minecraft 1.19.2 server running Fabric (fabric-server-mc.1.19.2-loader.0.15.3-launcher.0.11.2). I am unable to join the server, and I encounter a specific error on the client side.

Client-Side Error Message:
Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IllegalArgumentException: Unknown recipe serializer ic2:shapeless

Server-Side Logs:
[19:27:30] [Server thread/INFO]: BX joined the game
[19:27:33] [Server thread/INFO]: BX lost connection: Disconnected
[19:27:33] [Server thread/INFO]: BX left the game
Server and Client Setup:

Both the server and client have only IC2 and FabricAPI in the mods directory.
The same error occurs with Forge, but the server can be joined if IC2 is removed.
Could you please assist in identifying the cause of this issue? Is there any additional information that would be helpful for troubleshooting?

Thank you for your time and assistance.

I have been climbing inside the jar industrial craft 2 for some time, I found that if I delete the data/ic2/recipes folder, I can log in to the server, but industrial craft 2 is boring without recipes :D

I have the same problem. I suspect there is something wrong with the Fabric mount formula. I am using the latest build of industrialcraft-2-2.9.39+ex119-1.19.2-fabric.jar

I've try to make a mod to fix this bug, and it solves the problem to some extent.
My github repository is at here, you can try to use it.
