Error automation

I get an error while trying to add this automation:

- id: '164179246736942'
  alias: 'Hue light on gradually with alarm'
  hide_entity: False
  trigger:
  - platform: template
    value_template: '{{ states.sensor.time.state == states.sensor.alarm_clock_time_long.state }}'
    condition:
      condition: state
      entity_id: input_boolean.alarm_clock_status
      state: 'on'
    action:
      service: script.wake_up

Invalid config for [automation]: required key not provided @ data[‘action’]. Got None. (See /config/configuration.yaml, line 52).

THIS IS WHAT I HAVE IN LINE 52:
group: !include groups.yaml

and this:
The ‘hide_entity’ option near /config/automations.yaml:1426 is deprecated, please remove it from your configuration

Your indentation is wrong.

- id: '164179246736942'
  alias: 'Hue light on gradually with alarm'
  trigger:
  - platform: template
    value_template: '{{ states.sensor.time.state == states.sensor.alarm_clock_time_long.state }}'
  condition:
    condition: state
    entity_id: input_boolean.alarm_clock_status
    state: 'on'
  action:
    service: script.wake_up

I’m sorry I don’t understand what does “indentation” mean ?
what should I change

The number of spaces in front of the text.

I already fixed it for you above. In particular, look at the difference between your code and mine for “condition”, and “action”

understood, thank you!
