[koen-dev]

Preconditions (*)

1. Magento Commerce 2.3.0 beta32
2. Custom instance with custom attributes and attribute sets

Attributes used:

• Growth method: Dropdown
• Height: Dropdown

Steps to reproduce (*)

1. Create Product (Required fields + Categories)
2. Create Configurations for Product
3. Select Custom Attributes for Configurations
4. Select Custom Attributes Values
5. Skipped image uploading
6. Enter price for each configuration
7. Enter quantity for each configuration
8. Generate Products
9. Retrieve Category with products using GraphQL

{
  category(id: 5) {
    product_count
    products {
      items {
        name
      }
    }
  }
}

Expected result (*)

1. Category with products as name and product_count

{
  "data": {
    "category": {
      "product_count": 1,
      "products": {
        "items": [
          {
            "name": "Buxushaag kant-en-klaar"
          }
        ]
      }
    }
  }
}

Actual result (*)

1. Category with product_count matching Magento admin but without products

{
  "data": {
    "category": {
      "product_count": 1,
      "products": {
        "items": []
      }
    }
  }
}

Extra information

This isn't only related to CategoryTree it also happens with Products.
When retrieving the product using the REST API it works as expected.

Please, doublecheck that at least one simple product is in stock and has qty greater than zero.
This issue appears when the product is out of stock. The products count has a positive value but no products are on the list

[koen-dev]

@rogyar I can confirm this has been resolved by adding quantity to everything.

Also, this behavior is not the final one.
The product count value has been adjusted to reflect the fetched products number in the following PR
