Button.press service as action in a card help

Configuration
1

Hello,
I´ve tried the following to shutdown a PC as a hold_action in a lovelace card and get the Error message below.
When executing this code within the dev-tools / service it works.

Is there anything wrong on my side?

Thank you,
Philipp

        hold_action:
          action: call-service
          service: button.press
          target:
            entity_id: button.pc_livingroom_shutdown

Failed to call service button/press. must contain at least one of entity_id, device_id, area_id.

Where’s the rest of the card configuration? A button card should look more like:

entity: button.pc_livingroom_shutdown
show_name: true
show_icon: true
type: button
hold_action:
  action: call-service
  service: button.press
  service_data: {}
  target:
    entity_id: button.pc_livingroom_shutdown

sorry to bring up on old thread, I can’t get this work either.

update:
got it to wrk with

        tap_action:
          action: call-service
          service: button.press
          service_data:
            entity_id: button.hot_water_low
