    Hi nbo,

     

    Your definition can be simplified into:

     

    QueueMembers:
  type: object
  properties:
    members:
      type: array
      items:
        $ref: '#/components/schemas/QueueMember'

    Both empty and non-empty arrays will validate against this definition.

     

    To require an array to be non-empty, add the minItems: 1 attribute.
