Conditional cards not working?

Configuration
1

This is my code in ui-lovelace.yaml:

  - type: conditional
    conditions:
      - entity: switch.watch_tv
        state: "on"
    cards: 
      - type: vertical-stack
        cards:
          - type: horizontal-stack
            cards:
              - type: custom:button-card
                color_type: card
                action: service
                service:
                  entity-id: remote.harmony
                  device: 55198017
                  command: 1
                name: 1
                color: rgb(255, 131, 0)

and I get this error message:

Any idea what I am doing wrong?

I am not sure if conditional supports cards (plural)? Try “card” in line 5.

Ah, I see. I guess I should use a conditional card for every button then. Thanks!
