[bednar]

The self and org has to be defined in a nested object:

SecretKeysResponse:
      allOf:
        - $ref: "#/components/schemas/SecretKeys"
        - type: object
          properties:
            links:
              readOnly: true
              type: object
              properties:
                self:
                  type: string
                org:
                  type: string

as it is common in rest of API:

Source:
      type: object
      properties:
        links:
          type: object
          properties:
            self:
              type: string
            query:
              type: string
            health:
              type: string
            buckets:
              type: string

Organization:
      properties:
        links:
          type: object
          readOnly: true
          example:
            self: "/api/v2/orgs/1"
            members: "/api/v2/orgs/1/members"
            owners: "/api/v2/orgs/1/owners"
            labels: "/api/v2/orgs/1/labels"
            secrets: "/api/v2/orgs/1/secrets"
            buckets: "/api/v2/buckets?org=myorg"
            tasks: "/api/v2/tasks?org=myorg"
            dashboards: "/api/v2/dashboards?org=myorg"
            logs: "/api/v2/orgs/1/logs"
          properties:
            self:
              $ref: "#/components/schemas/Link"
            members:
              $ref: "#/components/schemas/Link"
            owners:
              $ref: "#/components/schemas/Link"
            labels:
              $ref: "#/components/schemas/Link"
            secrets:
              $ref: "#/components/schemas/Link"
            buckets:
              $ref: "#/components/schemas/Link"
            tasks:
              $ref: "#/components/schemas/Link"
            dashboards:
              $ref: "#/components/schemas/Link"
            logs:
              $ref: "#/components/schemas/Link"
