Problems regarding turning Sonos speaker off in an "and statement"

I’m about to make my first automation in HA, however, i’m having some trouble.
I would like to pause one of my Sonos speakers if it’s playing, everytime I’m starting a certain activity on my Harmony Hub. A rather simple automation I agree, but I haven’t quite gotten the hang of using HA yet. Hopefully one of you can help me. The code (so far) looks like this:

alias: Hvis Sonos i køkken spiller og TV tændes, sluk Sonos i køkken
description: ""
mode: single
trigger: []
condition:
  - condition: and
    conditions:
    -   - condition: device
    device_id: 3c006c438c097b07f662e75dd2701c12
    domain: media_player
    entity_id: media_player.kokken
    type: is_playing
     - condition: device
        device_id: 5775cdb70f507639cc6229e4a6b414c3
        domain: select
        entity_id: select.harmony_hub_activities
        type: selected_option
        option: Brug Nvidia Shield
action:
- type: pause
platform: device
    device_id: 3c006c438c097b07f662e75dd2701c12
    domain: media_player
    entity_id: media_player.kokken

I’m getting the error “Expected a dictionary @ data[‘condition’][0][‘conditions’][0]”

What seems to be the problem?
