Solved Internal Exception

Hey guys, I am currently developing a plugin. I planned in the next update I'll add ability to edit my plugin's messages thorugh config.yml. However when I 've done those things it is throwing Internal Exception when I execute the command.

Main class:

Code:

  
     FileConfiguration config;
    File cfile;
    private ArrayList<String> falling = new ArrayList<String>();
  
    public static String chatcolors(String message) {
      
    return ChatColor.translateAlternateColorCodes('&', message.replace("\\\\n", "\n").replace("\\n", "\n").replace("&nl", "\n"));

      
    }

  
    public void onEnable() {
      
        config = getConfig();
        config.options().copyDefaults(true);
        saveDefaultConfig();
        cfile = new File(getDataFolder(), "config.yml");
      
        Bukkit.getPluginManager().registerEvents(this, this)
    }
  

    @SuppressWarnings({ "null", "unused" })
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
      
      if (cmd.getName().equalsIgnoreCase("flytimer")) {
  
  
            if (!(sender.hasPermission("timer.fly"))) {
                String noperm = getConfig().getString("Global.nopermission");
                noperm = ChatColor.translateAlternateColorCodes('&', noperm);
                noperm = Main.chatcolors(noperm);
                sender.sendMessage(noperm);
                return true;
              
            }
            if (args.length != 2) { // Checks the arguments.
                String flyargs = getConfig().getString("FlyTimer.flytimer-args");
                flyargs = ChatColor.translateAlternateColorCodes('&', flyargs);
                flyargs = Main.chatcolors(flyargs);
                sender.sendMessage(flyargs);
                    return true;
            }

                String notonline = getConfig().getString("global.notonline");
                notonline = ChatColor.translateAlternateColorCodes('&', notonline);
                notonline = notonline.replace("%player", target.getName());
                notonline = Main.chatcolors(notonline);
                sender.sendMessage(notonline);
                return true;
            }
