i.e I have an object field

- name: cover
    type: object
    fields:
      - name: image
        type: image
        required: true
      - name: name
        type: string
        required: true

I expect cover itself is an optional, and if cover is being filled it should have name and image. However this configuration requires to fill the properties as required. I tried to set required to the object field itself but doesn't seem to change its behavior.

Is there something I miss to mark as a field as an optional?
