Service MediaPlayer/SelectSource shows error for missing data/source

Configuration
1

Hi Guys,

after the last update I have some issues with providing additional data to my services. I.E: the service MediaPlayer/SelectSource is now missing the data parameter:
image

This is how I am providing the data to the service:

tap_action:
  action: call-service
  service: media_player.select_source
  data:
    entity_id: media_player.spotify_maxi
    source: "Echo Küche"

This worked well until a few days ago, can you please help me what now could be wrong so that this service is not working anymore?

Best
Max

Short update on that: After going back to a previous backup everything runs fine again.
