Automation can not find service shell_command

Configuration
1

Hi, I ty to run a shell_command within an automation. Unfortunately, the automation tells me, that he can not find the service ( Error in describing action: e.services[i] is undefined). But from my point of view I do the configuration correctly. Whats my mistake?

configuration.yml:

# Loads default set of integrations. Do not remove.
default_config:

# Load frontend themes from the themes folder
frontend:
  themes: !include_dir_merge_named themes

#shell commands
shell_command:
  write_to_file: 'printf "%s {{ states(''sensor.wetterstation_temperatur'') }}, {{ states(''input_number.rain_counter_15_min_ago'') }}\n" "$(date "+%H:%M:%S")" >> /config/wetter.txt_$(date "+%Y%m%d")'
  

automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

automation.yml

- id: '1717099179496'
  alias: Wetterdaten_fuer_extern
  description: Speichert Regenmenge und aktuelle Temperatur aller 15 min in File.
  trigger:
  - platform: time_pattern
    minutes: /15
  condition: []
  action:
  - service: input_number.set_value
    metadata: {}
    data:
      value: '{{ states (''sensor.wetterstation_regenzahler'') | float }}'
    target:
      entity_id: input_number.rain_counter_15_min_ago
  - service: shell_command.write_to_file
    data: {}
  mode: single

Thanks for helping,
Holger
