NullPointerException

can anyone see why i'm getting a nullPointerException in this code? The stacktrace points to
addChants() on line "stack.addEnchantment(ench, level);"

Code:

    public static void giveKit(KitKat plugin, Player player, String kitName) {
        List<String> itemList = plugin.getConfig().getStringList("kits." + kitName + ".items");
        ListIterator<String> it = itemList.listIterator();
        if (it.hasNext()) {
            while (it.hasNext()) {
                String[] item = it.next().split(" ");
                int id = Integer.parseInt(item[0]);
                short meta = (short) Integer.parseInt(item[1]);
                int amount = Integer.parseInt(item[2]);
                ItemStack stack = new ItemStack(id, amount, meta);
                if (plugin.getConfig().getConfigurationSection("kits." + kitName + ".enchants").getKeys(false).contains(item[0])) {
                    ItemStack chantedStack = addChants(plugin, stack, kitName, item[0]);
                    player.getInventory().addItem(chantedStack);
                } else {
                    player.getInventory().addItem(stack);
                }
            }
        }
    }
   
    public static ItemStack addChants(KitKat plugin, ItemStack stack, String kitName, String item) {
        List<String> list = plugin.getConfig().getStringList("kits." + kitName + ".enchants." + item);
        ListIterator<String> it = list.listIterator();
        if (it.hasNext()) {
            while (it.hasNext()) {
                String[] chant = it.next().split(" ");
                Enchantment ench = Enchantment.getByName(chant[0]);
                int level = Integer.parseInt(chant[1]);
                stack.addEnchantment(ench, level);
            }
        }
        return stack;
    }

Also, I got a null pointer exception when I used..

Code:

if (ench.canEnchantItem(stack)) {
    //this gave null.....
}
// or when I do this....
int max = ench.getMaxLevel();
int min = ench.getStartLevel();
if ((level < min) || (level > max)) {
    //this gave null aswell......
}
