아이템을 우클릭하면 config에 저장된 어느 특정한 위치로 텔레포트하는 플러그인을 만들고 있습니다.

제 바람대로 빨간색 염료를 우클릭하면 텔레포트가 잘 되기는 하는데 Eventexception오류가 뜨네요...

왜 이러나요?

@EventHandler
public void warpCheckpoint(PlayerInteractEvent event) throws EventException {

    Player player = event.getPlayer();

    double x = plugin.getConfig().getDouble("Players." + player.getUniqueId() + ".x");
    double y = plugin.getConfig().getDouble("Players." + player.getUniqueId() + ".y");
    double z = plugin.getConfig().getDouble("Players." + player.getUniqueId() + ".z");
    float yaw = (float) plugin.getConfig().getDouble("Players." + player.getUniqueId() + ".yaw");
    float pitch = (float) plugin.getConfig().getDouble("Players." + player.getUniqueId() + ".pitch");

    Location tpLocation = new Location(Bukkit.getWorld("world"), x, y, z, yaw, pitch);

    String itemName1 = ChatColor.RED + "Back to checkpoint " + ChatColor.DARK_GRAY + "[" + ChatColor.GRAY + "Right-Click" + ChatColor.DARK_GRAY + "]";

    if (event.getAction().equals(Action.RIGHT_CLICK_BLOCK) || event.getAction().equals(Action.RIGHT_CLICK_AIR)) {
        if (player.getItemInHand() == null) return;
        if (player.getItemInHand().getItemMeta() == null) return;
        if (player.getItemInHand().getItemMeta().getDisplayName() == null) return;

        if (player.getItemInHand().getItemMeta().getDisplayName().equals(itemName1)) {
            player.teleport(tpLocation);
            return;
        }
    }

}
