BreakBlockAdv is a simple tutorial achievement I created, here is the code:

package com.ulxsth.achievementtest.achievements;

import com.fren_gor.ultimateAdvancementAPI.advancement.Advancement;
import com.fren_gor.ultimateAdvancementAPI.advancement.BaseAdvancement;
import com.fren_gor.ultimateAdvancementAPI.advancement.display.AdvancementDisplay;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.block.BlockBreakEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;

public class BreakBlockAdv extends BaseAdvancement {
    public BreakBlockAdv(String key, AdvancementDisplay display, Advancement parent, int maxProgression) {
        super(key, display, parent, maxProgression);

        registerEvent(BlockBreakEvent.class, event -> {
            Player player = event.getPlayer();
            if (isVisible(player)) {
                incrementProgression(player);
            }
        });
    }

    @Override
    public void giveReward(Player player) {
        ItemStack item = new ItemStack(Material.DIAMOND);
        ItemMeta im = item.getItemMeta();
        im.setDisplayName("とてもかたいだいやもんど");
        item.setItemMeta(im);
        player.getInventory().addItem(item);
    }
}

This is my first time writing an Issue, so please let me know if there are any flaws

Hi! I tested the code and it seems to work, in our opinion the error should be looked for in other classes, could you send us the main class of the plugin?

[ulxsth]

I just tested it under the same conditions and didn't get the same error. So this may not be an error with this plugin :(

In the meantime, here is the repository for the plugin that implements BreakBlockAdv:
https://github.com/ulxsth/AchievementTest

Did you reload before getting the error?

[ulxsth]

The reason why the errors start occurring is not well understood, but the behavior after various restarts is as follows:

• /reload confirm after the error occurs: the error continues to occur
• Shutting down the server and starting it again after the error occurs: error subsides.

[ulxsth]

I said "with sword" but in fact it was no different with other things in my hand.

[davidebilardello]

We know very well that doing /reloads may break some features! So we recommend that you restart the server every time. However we are leaving your issue open because we will make changes to fix some things about it.

[ulxsth]

I understand! Thanks for your thoughtful response <3
