Picture-glance card no longer working

A few days ago I noticed that my cameras have stopped working on lovelace.

lovelace

This seems to be related to version 0.107.7 but I’m not 100% sure of that as I’m not sure when it started. Has anyone got any ideas on how to fix this, please?

Extract from ui-lovelace.yaml. This has not been changed since it worked.

  - title: Front Cam
    cards:
      - type: custom:layout-card
        layout: horizontal
        cards:
        - type: picture-glance
          title: Doorbell
          entities:
          - binary_sensor.pir_doorbell
          camera_image: camera.doorbell
        - type: picture-glance
          title: Front Door
          entities:
          - binary_sensor.pir_doorbell
          camera_image: camera.frontdoor

Thanks very much for any assistance.
