[1.20.1 Forge] Console error when sending anything into chat

[slava110]

Hi. When I'm trying to send mod icon to the chat, it sends empty space instead. And in console I see:

[09:50:04] [ForkJoinPool.commonPool-worker-1/ERROR] [inline/]: Unknown image type at url: union:/D:/MCPrismData/instances/LetroTech%20Dev/minecraft/mods/create-1.20.1-6.0.4.jar%23262!/icon.png

When I'm trying to send vanilla minecraft mod icon, it sends question mark and shows console error:

[SamsTheNerd]

don't know what's up with the second part, but the first part is fixed in-dev. Is that second one being logged on the server?

[slava110]

Second error actually happens when I write any message to the chat but only once. I'm on integrated server in a modpack with many mods. Could be incompatibility, can't check right now, I can test in an instance with just inline mod later

[slava110]

Tested on Inline-only instance.
Forge 47.4.0, Inline 1.20.1-1.2.0
Error occurs when I write anything into chat. Integrated server (singleplayer world)

I can open separate issue for that if you want since it's not about mod icons as I've discovered

[SamsTheNerd]

can just rename this one 🤷‍♀ that's a real weird error.
i'll look when i have more time. if you wanna poke at it more i'd check:

1. reproducible on fabric?
2. reproducible on 1.21.1?

[slava110]

This problem is only present on Forge 1.20.1. It isn't present on Fabric 1.20.1 and NeoForge 1.21.1. I didn't test Fabric 1.21.1 but I think it's safe to assume that problem isn't present there as well

[PikachuGabe]

been having this issue too on Minecraft v1.20.1 inline v1.1.1 forge v47.4.0 so I've been dissecting the mod's code on both Github and a decompiler to see what could possibly be causing it. I honestly can't figure it out for the life of me though, so it could very well be Forge jank or Forge not liking that MatchContextImpl references itself. Either way, something in MatchContextImpl or Forge is preventing it from finding MatchContextImpl from my understanding and I'm not sure if it's fixable.

[1luik]

You can refer to some similar bugs on Bukkit Forge servers

[1luik]

For example, modifying code details

[1luik]

Or you can ask Forge or suspect JVM. I have replicated this bug before
