Pages Section show only parent template

Hey, I have a page section at site.yml where I want to display all child pages with the template “variation-from-base-product”.

The page structure is:

  • base-product
    – variation-from-base-product

The page “variation-from-base-product” is a child of the page “base-product”. Unfortunately, only the pages with the template “base-product” are displayed in the page area. The childpages are not displayed.

This is my blueprint:

    sections:
      products:
        type: pages
        template:
          - variation-from-base-product

The parent property is missing, indicating base-product as the parent.
