Hello to everyone :smiley:

I want to call a one script from automation but i have this error:

TestNotificaAlexa: Error executing script. Unexpected error for call_service at pos 1: Error rendering data template: UndefinedError: 'None' has no attribute 'attributes'

The automation:

- id: '1601037095611'
  alias: TestNotificaAlexa
  description: ''
  trigger: []
  condition: []
  action:
  - data:
      entity_id: script.01notifiche_alexa_e_app
      variables:
        message: "Attenzione!!! ALLARME ATTIVATO!! Effettuata Chiamata a Forze Dell'Ordine...\

The script:

  - service: media_player.volume_set
    data:
      entity_id: media_player.echo_dot_di_marco
      volume_level: 0.5

Can someone help me please?
Thanks

Hi Stefano,
Since when do you experience this issue?
‘data_template:’ is not supported anymore since 0.115, this should be ‘data:’ now.

In case this happens since the upgrade to 0.115.x, I’d fix that at first.

Thanks for your reply, so the correct way is this:

01notifiche_alexa_e_app:
  sequence:
  - service: media_player.volume_set
    data:
      entity_id: media_player.echo_dot_di_marco
      volume_level: 1
  - delay: 00:00:02
  - data:
      data:
        method: all
        type: announce
      title: '{{ title }}'
      message: '{{ message }}'
    service: notify.alexa_media_echo_dot_di_marco
  - delay: 1
  - data:
      data:
        type: push
      title: '{{ title }}'
      message: '{{ message }}'
    service: notify.alexa_media_echo_dot_di_marco
  - service: media_player.volume_set
    data:
      entity_id: media_player.echo_dot_di_marco
      volume_level: 0.5

Is correct?

No, just one data. I’d say:

 - data:
      type: push
      title: '{{ title }}'
      message: '{{ message }}'
    service: notify.alexa_media_echo_dot_di_marco

In one of my automations:

  - data:
      msgtext: Hi, the radio and the TV are on now, let me turn it off
    service: script.tv_message

Yaml
I will edit the yaml

You could edit it in the GUI and then switch to YAML view.
It might be of help with assuring the correct ident.

Edit: Since this was pointed as the solution, let me add the actual solution.
