Error on checkTime() functio

I have a function that checks the time of the world and calls an event

Code:

    public void checkTime(){
   
        if(Bukkit.getServer().getWorld("Survival2").getTime() > 13000 && Bukkit.getServer().getWorld("Survival2").getTime() < 23000){
                for(Player p: Bukkit.getServer().getOnlinePlayers()){
                    //change player
                   
                    if(getCurse(p).equalsIgnoreCase("werewolf")){
                        if(getWerewolfState(p) == false){
                            transformWerewolf(p, true);
                        }
                        }
                    }
            }else{
                for(Player p: Bukkit.getServer().getOnlinePlayers()){
                    //change player
                    if(getCurse(p).equalsIgnoreCase("werewolf")){
                        if(getWerewolfState(p) == true){
                            transformWerewolf(p, false);
                        }
                        }
                    }
            }

"getCurse"

What?

 

sorry the function getCurse is:

Code:

    public String getCurse(Player player){
        String result = "";
        try{
            File players = new File(getDataFolder(), "players.yml");
            FileConfiguration curses = YamlConfiguration.loadConfiguration(players);
            result = curses.getString("Players.Curses." + player.getDisplayName());
           
            return result;
        }catch(Exception e1){
            e1.printStackTrace();
            return result;
        }
    

just an update I just found that the error is in getCurse, I believe it has to do with the getString() function what could be causing this? I read something about including it in my jar file but that can't be right.
