Server doesn't accept modified chat message

[szviktor]

Hello!

I tried to modify my chat messages in my server-side only mod, but everytime the server keeps giving me the following error:
 

[net.minecraft.server.network.ServerGamePacketListenerImpl/]: szviktor sent message with invalid signature: '[default] szviktor: sarasf'

The code I tried to use:
 

	@SubscribeEvent
	public static void onChat(ServerChatEvent event) {
		Player player = event.getPlayer();
		UserManager userManager = LuckPermsProvider.get().getUserManager();
		User user = userManager.getUser(player.getUUID());
		CachedMetaData data = user.getCachedData().getMetaData();

		event.setComponent(Component.literal(
				"[" + data.getPrimaryGroup() + "] " + player.getName().getString() + ": " + event.getMessage()));
	}

And I'm currently using the version 1.19-41.0.25.
Sadly, I can't upgrade the version, because LuckPerms has some issues on newer versions such as 41.0.108, and so on, and right now, I don't know what should I really do.

ServerChatEvent was overhauled in the 1.19.1 update to support the secure chat system, it's probably not going to be possible to fix this without updating to 1.19.1 or 1.19.2.

Thank you!
I think, now I understand the problem. 😆
Let's hope, they will update the mod to 1.19.1...
