Query for content relationship documents within group fields

Similar to this topic, can anyone offer some insight into how to query for content relationship documents within group fields?

I have a custom type with repeatable groups which contain a content relationship field. I am able to query these fields using fetchLinks, but like the linked topic above, fetchLinks only returns the first object in a Rich Text field's array.

JSON for the about_page custom type:

{
  "id": "about_page",
  "label": "About Page",
  "repeatable": false,
  "status": true,
  "json": {
    "Main": {

        "type": "UID",

This query is not returning any of the subfields for the meeting_tabs custom type:

async function init() {
  const page = await client.getByUID('about_page', 'about-meetings',
  {
    graphQuery: `{
      section {
        meeting_tabs {
          ...on meeting_tabs {
            ...meeting_tabsFields
          }
        }
      }
    }`
  }
  )
  return page
}

init()

Hello @jgunderson

Thanks for reaching out to us.

I think your graphQuery should like this:

{
  meeting_tabs {
    ...your_custom_typeFields
    previous_meeting_documents {
      document_link {
        ...on media {
          ...mediaFields
        }
      }
    }
  }
}

Please follow our technical reference for graphQuery: GraphQuery API Option Technical Reference - Documentation - Prismic

Thanks,
Priyanka

Thank you @Priyanka.

I just solved this by adding the Custom Type (about_page) and then the group API ID (section):

      about_page {
      section {
        ...sectionFields
          content_relationship {
            ...on meeting_tabs {
              ...meeting_tabsFields
            }
          }
}
}
