Querying a relationships group fields returns null in GraphQL

[DanWebb]

Describe the bug
Using graphql, when querying a relationship + a group field inside the relationship the group field returns null.

For example...

query group_fields_in_relationship {
  parent(where: { some_prop: "some_value" }) {
    id
    related_content_type {
      group_field {
        title
      }
    }
  }
}

parent.related_content_type.group_field will be null

But, if I query the related_content_type directly the group_field returns correctly.

Steps to reproduce the behavior

1. Create a group field and add it to a content type
2. Relate the content type with a group field in it to another content type
3. Try to query the group field through the content type relationship
4. See the group fielod in the query return null

Expected behavior
The group field to return what it contains

Hello @DanWebb !

Thank you for this report! I can confirm this issue.
We will do our best.

Comment on that, since I think it's related: Also the JSON response via REST API does not contain group based fields or the group reference itself within the relationships.

(And: Groups are really a cool feature.)

See also #4459.

Would be good to get an ETA on this or whether anyone is working on it. It's a bit of a blocker. Happy to jump in and give it a go!

If you are using the REST API - here is a workaround.
Custom populate relations
