Make sure you use the latest version of Corail Tombstone, if you already use the latest version talk to the Mod author.

What did you do that this error happen, joining a single player world a server, ..? Sorry for being unclear.

If you using JourneyMap, make sure you use a version for 1.19.2. If you not use JourneyMap or if the error remains please post debug.log. On CurseForge you need to enable the debug.log in the settings.

Ah, sorry i mean where?

Where did you get this error?

First of all remove OptiFine and download a compatible 1.19 version. Then try again, if there are still problems post new debug.log.

You now check first if you're on server, then check if your on client (which will never be true since your on already on server). Inside the client only block you call the Particle code from server and client, that's not how it's work. In addition you create a Field in your Item class which is never be initialized, remove these Field your Item is a singleton the Data will be shared between all Items. Your code is server side so you only need to call ServerLevel#sendParticles. You can get the ServerLevel from casting the Level which is given in the method, after a server side check.

Please post the full code (at least the method), just a piece of code is not helpful.

In the code you never spawn particles. But I suspect you are calling Level#addParticle server side, which will perform no action since there is no server side implementation. If you want to call the particle spawn code server side you need to use ServerLevel#sendParticles.

Okay i understand this use case but why did you not set the Players how lose in Spectator Mode? Show what you have tried.

Your version of Architectury is written for a older version of Minecraft, I assume for 1.19.1.

This will not work Create is a Mod which is required on both sides (server and client). You can only use client side Mods on a non Modded server, (like Optifine).

Show more of your code.

If you using CurseForge you need to enable the debug.log in the settings.

What did you really try to achieve, a Life steal mod is something completely different? Why do you want to ban a player, this should be still a admin operation?

On CurseForge you need to enable the debug.log in the settings.

How did you suspect that OptiFine 1.18.2 works on 1.19? Please post debug.log from the logs folder.

Please post debug.log from the logs folder.

This error is often indicative of an outdated Java version. Please ensure your Java version is up to date. You can download OpenJDK from the Adoptium project. If the error persists after updating your Java version, please post the updated installer log as well as the contents of %windir%\system32\drivers\etc\hosts (Windows) or /etc/hosts (Mac, Linux).

Please post installer log.

Create your own thread and post debug.log from the logs folder.

Please post launcher_log.txt.

Probably you mean Entity#getPersistentData, if you want to store data in this CompoundTag, create a second CompoundTag store there all data you want to store then put this CompoundTag with your mod id as key into the PersistentData of the Entity. But i would highly recommend you to use a Capability, see: https://forge.gemwire.uk/wiki/Capabilities.

Please post debug.log from the logs folder. On CurseForge you need to enable the debug.log in the settings.

Could you please provide a bit more context, like what version you are talking about, what was the usage of the method and what was the return type?
