          - type: object
            properties:
              type:
                const: FEED_DATA
              events:
                description: Batch of events.

                      List of events in full mode.
                      Empty fields are omitted from the json.
                    type: array
                    items:
                      - $ref: "#/components/schemas/FeedEvent"

items doesn't accept a list per spec, the dash - should be omitted.
