I am trying to load all variations of a product.

While using google I found this code snippet:

```auto
class ProductViewSubscriber implements EventSubscriberInterface
{
    private EntityRepositoryInterface $productRepository;

    public function __construct(EntityRepositoryInterface $productRepository)
    {
        $this->productRepository = $productRepository;
    }

    public function getVariantsOfProduct(SalesChannelProductEntity $product, Context $context): EntitySearchResult
    {
        $parentProduct = $product->getParent();
        if ($parentProduct != null) {
            // We need the parent product to find all variants
            $product = $parentProduct;
        }
        $criteria = new Criteria();
        $criteria->addFilter(new EqualsFilter('product.parentId',
            $product->getUniqueIdentifier()));
        return $this->productRepository->search($criteria, $context);
    }

    public static function getSubscribedEvents(): array
    {
        return [
            ProductPageLoadedEvent::class => ['addVariants'],
        ];
    }

    public function addVariants(ProductPageLoadedEvent $pEvent)
    {
        $products = $this->getVariantsOfProduct($product = $pEvent->getPage()->getProduct(), $pEvent->getContext());
        $matchingVariants = $products->getElements();
    }
}

```

But using the code snippet only an empty list is returned, though there are definitely variants to that product. How can I fix this code?

change `new EqualsFilter('product.parentId',` to `new EqualsFilter('parentId',`
