Solved PlayerInteractEvent error

Hello there! I was trying to do an kit Gui (with kits) basically when the player clicks on the kit it does "/kit (nameofthekit)"
When players enter the server they come with an chest that when right clicked it opens that GUI.
but every time a player clicks on that chest it pop-ups an error in the console and the GUI doesn´t open.
Its an 1.8.8 server

GUI:

Code:

package Guis;

import org.bukkit.entity.*;
import org.bukkit.*;
import java.util.*;
import org.bukkit.inventory.*;
import org.bukkit.inventory.meta.*;

import Outros.KillsDeathsRankXp;

import org.bukkit.event.inventory.*;
import org.bukkit.event.*;
