Hello!

Hopefully someone here can help us out with the following.

**What we want to achieve:**  
Display some products from a specific productcategory below the shopping cart ({url}/checkout/cart).

**Our idea:**  
Fetch the products via an Event Subscriber that add the data to the pagelet for use in the template; as explained here:  
[https://docs.shopware.com/en/shopware-platform-dev-en/how-to/add-data-to-a-storefront-page](https://docs.shopware.com/en/shopware-platform-dev-en/how-to/add-data-to-a-storefront-page)

**The problem:**  
While trying to fetch a category (by ‚name‘ / or ‚active == 1‘ for example)&nbsp;and it’s assosiated products, we get the following 500 error:

_MappingEntityClassesException - ‚Mapping definition neither have entities nor collection.‘_

Somehow the same code (follows below) works fine when we try to access the **productRepository** instead of the **productCategoryRespository**.

Can someone please help us out?

Thank&nbsp;you in advance!

_Code snippets follow below._

**UpsellSubscriber.php**

```
productRepository = $productRepository;
        $this->productCategoryRepository = $productCategoryRepository;
    }

    public static function getSubscribedEvents(): array
    {
        return [
			FooterPageletLoadedEvent::class => 'getProductsFromCategory'  
        ];
    }

    public function getProductsFromCategory(FooterPageletLoadedEvent $event): void
    {
		$criteria = new Criteria();
		//$criteria->addFilter(new EqualsFilter('name', 'Minicontainer'));
		$criteria->addFilter(new EqualsFilter('active', '1'));

		$entities = $this->productCategoryRepository->search(
			$criteria,
			$event->getContext()
		);

		var_dump($entities);
		die();

		//$event->getPagelet()->addExtension('custom_upsell', $category);
    }
}

```

Hi!

Try to revert the code to&nbsp; **productRepository&nbsp;** and filter on a specific category id.

Have you found a solution?  
I am having a similiar problem. I am trying to get the name(s) of a dynamic product group of a product.
