YouTube app opens on TV using webostv integration but no video plays

I am trying to play a YouTube video on my TV with webostv integration using webostv.command service. When I run the script YouTube app opens on TV but no video plays.
My code is the following:

tv_livingroom_youtube:
  alias: "Play YouTube video"
  sequence:
    - service: webostv.command
      target:
        entity_id: media_player.tv_livingroom
      data:
        command: system.launcher/launch
        payload:
          id: youtube.leanback.v4
          contentId: CUc6NEEbbeo

Can someone help me to solve the problem?

Thanks

Did you manage to solve the problem? Did it work for you? He doesn’t want to work for me in any way. Created issues LG webOS SmartTV (LG 32LM6350) - YouTube content doesn’t launch

I checked on the LG 43UK6750 TV. The LG 43UK6750 TV has webOS 4 and the code below worked, and the LG 32LM6350 TV has webOS 4.5 and it doesn’t work there. Probably the integration cannot fully control the LG 32LM6350 TV

service: webostv.command
data:
  command: system.launcher/launch
  entity_id: media_player.tv_lg_na_kukhne
  payload:
    id: youtube.leanback.v4

Hello! Try with the following example.

tv_livingroom_youtube:
  alias: "Play YouTube video"
  sequence:
    - service: webostv.command
      data:
        entity_id: media_player.tv_salon
        command: system.launcher/launch
        payload:
          id: youtube.leanback.v4
          contentId: "https://www.youtube.com/tv?v=CUc6NEEbbeo"
      entity_id: media_player.tv_salon

Hope it helps.
