I get this error: 'NoneType' object has no attribute 'proxy'

[llego]

Hi, I get the error below when launching a script. I'm on the latest version of Home Assistant. Do you know what's going on?

Here's the script I'm trying to run:

alias: Cast yleareena to My Chromecast
sequence:
  - data:
      entity_id: media_player.google_nest
      media_content_type: cast
      media_content_id: ' { "app_name": "yleareena", "media_id": "1-4521287" }'
    service: cast_extensions.play_media
mode: single

Here's my configuration.yml:

cast_extensions:
  areena_key: app_id=zzzzzzz&app_key=zzzzzzzzzzzzzzzzzzzzzzzzz

Yle areena support might be broken by updates (along with other things). I'll need to try it

Thanks! Note that I haven't tried this script before. I just installed it. I'm trying to set up a button in Lovelace that plays the latest episode of DJ Lux from Yle Vega :)
