Create automation to disable Yeelight using button

Configuration
1

I simple want this, I press button, light go on, press again, lights go off.

Problem is, while checking my automation it says that " Error loading /config/configuration.yaml: mapping values are not allowed here
in “/config/automations.yaml”, line 21, column 18

Could you help?

- alias: 'Ligar Luzes da Sala quando botao pressionado'
  trigger:
    platform: event
    event_type: click
    event_data:
      entity_id: binary_sensor.switch_158d0001d62b0d
      click_type: single
  action:
    service: light.turn_on
    entity_id: light.yeelight_rgb_7811dca6009f

Your indentation is wrong in condition.

    condition:
      - condition: state
        entity_id: light.yeelight_rgb_7811dca6009f
        state: 'on'

But you should use one toggle automation instead of these two light.turn_on and off.
