How to cast a doorbell image to chromecase

I try to start an automation that casts an image from my doorbell to my google nest hub.

But this is not working.

description: ""
mode: single
trigger:
  - platform: state
    entity_id:
      - binary_sensor.doorbell_motion_detected
      - binary_sensor.doorbell_person_detected
      - switch.doorbell_motion_detection
      - camera.doorbell
    from: null
condition: []
action:
  - service: media_player.play_media
    target:
      entity_id: media_player.living_room_display
    data:
      media_content_type: image
      media_content_id: "{{ states('image.doorbell_event_image') }}"
alias: test doorbel image

My living room display indicates that a stream is starting but no image is displayed.

i can see the image in my browser but it seems like i can not cast it.

Anybody got an idea on how to do this?
