Internal Exception: io.netty.handler.codec.DecoderException: net.minecraft.ResourceLocationException: Non [a-z0-9/._-] character

[agentbl0x]

the mods that the error list work fine on their own, but once i update/add more mods they begin to bug out, heres the debug.log: https://gist.github.com/cheeseisthegreatestfoodevermade/f80ad37378ff666bb2026e0394bc2579

One of your mods has broken networking.

Neither the error you posted or the log says which one.

Since you are adding mods, it is likely one of the mods you just added.

 

You can try adding

Quote

-Dforge.logging.mojang.level=debug

to the "additional arguments" in curseforge's minecraft settings.

This will print the full error to the debug.log which might have more information?

But usually errors at the protocol level like the one you have, don't show which mod is causing the problem.

[04Apr2023 12:02:05.166] [Render thread/DEBUG] [mixin/]: Mixing block.hopper.ClassInstanceMultiMapMixin from canary.mixins.json into net.minecraft.util.ClassInstanceMultiMap

Optimisation mods like canary are usually a good bet.

Although they might work fine by themselves, they cause all sort of conflicts with other mods because of changes they make to how minecraft works.

I removed canary, pluto, smoothboot, and saturn but I've still got the error, I could post the servers logs as i run it? Here is the new log (with the additional argument): https://gist.github.com/cheeseisthegreatestfoodevermade/f80ad37378ff666bb2026e0394bc2579

That narrows it down to something with a broken RecipeSerializer, but does not identify the mod.

 

There are warnings just before where create is complaining about broken recipes from "createchromaticreturn"

it isn't chromatic return, i just tested it now. should I try enabling and disabling create addons until I find the mod breaking it?

[warjort]

It isn't necessarily create related.

All I can tell you is something has broken recipe (de)serialization logic, that is messing up the transfer of recipes from the server to the client.

Without an error identifying the mod, the only way you will find it is to experiment with removing mods until the problem goes away.

Backup your world(s) before removing mods.
