Sonos Scene

After a recent upgrade, a lot of my automations and scenes stopped working. I have fixed quite a few of them but starting my Sonos with a scene is still not working. Any guesses as to what might be wrong with this snippet out of my scenes.yaml?

- id: 'xxxxxx'
  name: Bedtime
    media_player.bedroom_sonos:
      volume_level: 0.15
      media_content_id: x-sonos-http:song%3a1243558167.unknown?sid=204&flags=0&sn=2
      repeat: one
