Custom image in picture-entity card not shown

Configuration Frontend
1

Hi, my target is to show all persons in my home with a picture-entity card without the persons state, when the persons are “not_home” greyed out, but with persons state within the picture.

I have now created a grid setup with conditional cards and picture-entity’s.
My problem is that image i have configured within the picture-entity cards are not loaded. In all cases the images from the person is shown, also when i have configured a picture manually.
Does anyone have an idea? It is my first post here, so yo can believe my, i am really confused :sweat_smile:

This is my code:

type: grid
square: true
columns: 3
cards:
  - type: conditional
    conditions:
      - condition: state
        entity: person.dennis
        state: home
    card:
      show_state: false
      show_name: false
      camera_view: auto
      type: picture-entity
      aspect_ratio: "1"
      image: /api/image/serve/53a7395b140ed6c1673bc67ba1403081/512x512
      entity: person.dennis
  - type: conditional
    conditions:
      - condition: state
        entity: person.dennis
        state_not: home
    card:
      show_state: true
      show_name: false
      camera_view: auto
      type: picture-entity
      entity: person.dennis
      aspect_ratio: "1"

I have also checked the image by copy and paste them into the URL and the picture is shown there as expected.
