[SOLVED] Service_template syntax (set an input boolean based on binary sensor state)

Configuration
1

EDIT: It was a sensor issue, the script actually is working.

Hi all,
I have a script in which I’m trying to turn ON or OFF an input boolean depending on the state of a binary sensor.
Which is the correct syntax? cause I’ve tried different solution found on the forum but they all doesn’t work.
This is the last one I tried

...

- service_template: "{% if is_state('binary_sensor.soil_1' , 'on') %} input_boolean.turn_on {% else %} input_boolean.turn_off {% endif %}"
  entity_id: input_boolean.soil_01

...

thanks
