        service: script.turn_on
        target:

        data:
          message: >-
            Hello Doordell - A Person Detected. Device ID. /{{
            trigger.event.data.device_id }}/ Trigger ID
            /{{trigger.event.data.nest_event_id }}/
          data:
            entity_id: camera.hello_video_doorbell
            image: >-

              trigger.event.data.nest_event_id }}/thumbnail
            video: >-
              /api/nest/event_media/{{ trigger.event.data.device_id }}/{{
              trigger.event.data.nest_event_id  }}

variables:
  t: "{{ now().strftime('%Y-%m-%d %H-%M-%S') }}"
  d: "{{ t[:10] }}"

The clip and image do not show up on the notifications of iPhones nor iPads. I can read the Device ID and Trigger ID are sent in the notification. Please let me know how to fix it. Thanks in advance.
