Casting Google YouTube Video Playlist

I have a script that I’ve seen work yesterday evening. It kickoff a YouTube video playlist.

alias: Youtube Hardcode_kidrock
sequence:
  - service: media_player.play_media
    target:
      entity_id: media_player.wcast_tv
    data:
      media_content_id: >-
        {"app_name": "youtube", "playlist_id":
        "PLJ2hx9Xyf-QpN0qhaLJjaiMKgz2kyBM2x", "media_id": "MOWDb2TBYDg"}
      media_content_type: cast
mode: single

This morning I ran it again and I get a message saying the Youtube video has been triggered.

I see the following in the related logbook entries:
Youtube Hardcode_kidrock turned on followed by
Youtube Hardcode_kidrock turned off triggered by state of Youtube Hardcode_kidrock turnon

In any case the playlist does not start .

Any ideas why this may be sporadically happening ? Does the second log entry indicate that the script is canceling itself ?

Any help greatly appreciated.
