Solved InventoryTransactionEvent problem

Hello, I have tested my code but nothing is happening... Why ?

PHP:

    public function onTransaction(InventoryTransactionEvent $e)
    {

        $transactions = $e->getTransaction()->getInventories();
        $player = null;
        $chestinv = null;
        $action = null;
        $item = null;
        foreach ($transactions as $transaction) {
            $inv = $transaction->getHolder()->getInventory();
            if ($inv instanceof ChestInventory) {
                foreach ($inv->getViewers() as $assumed) {
                    if ($assumed instanceof Player) {
                        $player = $assumed;
                        $chestinv = $inv;
                        $action = $transaction;
                        break 2;

                    }
                }
            }
            foreach ($e->getTransaction()->getActions() as $inventoryAction) {
                $item = $inventoryAction->getSourceItem();

            }

            if (is_null($player ?? $chestinv ?? $action)) {
                return;
            }

            if ($action instanceof SlotChangeAction) {


                $slot = $action->getSlot();


                $this->Shopbuy($player, $item, $chestinv, $slot);
            }
        }
    }
