I am trying to get the SKU of a product, but I just can't find out how to correctly use \Magento\Catalog\Api\ProductRepositoryInterface. It works when i use the getList() method, but getById() leads to a timeout (see the following code):

class LiveItem extends \Magento\CatalogInventory\Model\Stock\Item
    public function __construct(
        \Magento\Catalog\Api\ProductRepositoryInterface $productRepository,
        ... more DI
        $this->productRepository = $productRepository;

    public function getQty()
        //this works:
        foreach (($this->productRepository->getList(
        )->getItems()) as $item)
            var_dump($item->getId()); //$item->getSku() works as well

        //but this doesnt (4696 definitely exists according to the var_dump output above):

Can someone help me in finding out what's going on here? I'm on Magento 2.2.1

Is there another way to get the product's SKU?


getById return object of \Magento\Catalog\Api\Data\ProductInterface.

Try this code:

/** @var \Magento\Catalog\Api\Data\ProductInterface $product */
$product = $this->productRepository->getById(4696);

Write me if you have any issues.

  • Thanks Evgeny, this works! I assume I can't var_dump the whole $product because it consumes to much memory - am I right? – bayer Nov 19 '17 at 10:45
  • Yes, of course. You are right :) – Evgeny Levinsky Nov 19 '17 at 10:48
