When i join the server of my minecraft it says Network configuration task not seupported: spell_engine:config

and the console errror is :-

Having the same issue! I am using Neoforge + Sinytra

Has there been a fix for this issue? I am running into it as well!

Same here

I have a debug message :

fabric_networking_api_v1: Class version 65 required is higher than the class version supported by the current version of Mixin (JAVA_17 supports class version 61)

If that can help

I am afraid this issue is caused by Sinytra Connector incorrectly implementing network config stage handler registrations.
I'll have to investigate.

My friend is having the same issue, but we don't have a Forge server, it's running on Fabric. The error code is exactly the same, what would be the issue then?

This is a confirmed issue of Forgified Fabric API (a component of Sinytra Connector).
I am unable to take any actions, since my usage of the original Fabric API is correctly coded.

Awaiting fix from Forgified Fabric API.
Sinytra/ForgifiedFabricAPI#171

Solved by FFAPI update.

RPG Series via Sinytra Connector is now fully playable.
