Oque tem de errado neste código?

I was making a plugin that sells enchanted items in the gui plus the 2 item is giving an error when setting the charm what can it be?

PHP:

if ($itemClicked->getId() == 745) {
            if ($player instanceof Player) {
      $cash = $this->eco->myCash($player);
            if($cash >= 300){
                $this->eco->removeCash($player, "300");
    $inv = $player->getInventory();
$enchantment1 = Enchantment::getEnchantment(16);
$enchInstance = new EnchantmentInstance($enchantment1, 2);
$pik = Item::get(345, 0, 1);
$pik->addEnchantment($enchInstance);
$inv->addItem($pik);
$player->sendMessage("§aCompra com sucesso");
            }else{
                $player->sendMessage("§aVocê não tem cash para comprar esse encantamento");
            }
            }
            return true;
        }
        if($itemClicked->getId() == 743) {
            if($player instanceof Player) {
$cash = $this->eco->myCash($player);
            if($cash >= 300){
                $this->eco->removeCash($player, "300");
    $inv = $player->getInventory();
$enchantment2 = Enchantment::getEnchantment(14);
$enchInstance = new EnchantmentInstance($enchantment2, 3);
$esp = Item::get(743, 0, 1);
$esp->addEnchantment($enchInstance;
$inv->addItem($esp);
$player->sendMessage("§aCompra com sucesso");
            }else{
                $player->sendMessage("§aVocê não tem cash para comprar esse encantamento");
            }
            }
            return true;
        }

 

I wonder too, what error could it be!
