No server support in 1.20.1, prevents any joining

[scras453]

Adding this mod to a server completely prevents other players from joining said server even if the mod versions are the same. Tested on an isolated server with just the "jineric-b6.3.1+1.20.1.jar" jar file and fabric api v 0.90.7 jar on the server and client.
Error provided while joining:
java.lang.NullPointerException: Cannot invoke "net.minecraft.class_2960.toString()" because "$$0" is null

Could be just the version of fabric api? Havent tested

Do the latest version of the mod also have this issue? I would advise updating to the latest if you can. I think it's either 1.21.4 or .5 currently. I'm working on updating to 1.21.6.
