I'm pretty sure I have the spec added to my chatgpt agent properly. so in an effort to fix the issue I tried changing the play_music script from ...

alias: Play Music
sequence:
 - variables:
     music_query: "{{ music_query | default('Queen') }}"
     mass_media_player: "{{ mass_media_player | default('media_player.workshopsatellite') }}"

to

alias: Play Music
sequence:
  - variables:
      music_query: "{{ music_query | default('Metallica') }}"
      mass_media_player: media_player.workshopsatellite

and that seemly solves the issue. am I doing something wrong or did I configure something wrong to make Template variable warning: 'mass_media_player' is undefined when rendering '{{mass_media_player}} happen?

[MrSco]

I tried the (OPTIONAL, USE AT YOUR OWN RISK) Below is a slighly modified play_music script also and it also like described, allows playing without saying "in the workshop" but gives the same error in the logs...
