Stepper motor doesn't work

Configuration

I was trying to add a stepper motor in esp home following this https://esphome.io/components/stepper/index.html I get a error code in the logs.

this is that error

Logger: homeassistant.config
Source: config.py:454
First occurred: 16:51:21 (1 occurrences)
Last logged: 16:51:21

Invalid config for [automation]: required key not provided @ data['action']. Got None. (See /config/configuration.yaml, line 5).

for the motor I added this to the automations file.

- alias: Write Stepper Value to ESP
  trigger:
  - platform: state
    entity_id: input_number.stepper_control
    action:
    - service: esphome.testing_control_stepper
      data_template:
        target: '{{ trigger.to_state.state | int }}'

your indentation is incorrect (and you don’t need “data_template” just “data”):

- alias: Write Stepper Value to ESP
  trigger:
  - platform: state
    entity_id: input_number.stepper_control
  action:
  - service: esphome.testing_control_stepper
    data:
