Template error

[BrunoKrugel]

Hey! First of all, fantastic app, just bought the lifetime upgrade.

I am trying to use the notification blueprint from the example:

use_blueprint:
  path: Trooped/notification.yaml
  input:
    title: Laundry's done!
    message: Take it out of the washing machine
    mdi_icon: mdi:washing-machine-alert
    color:
      - 140
      - 208
      - 230
    length: 20
    interrupt: true
    sound_url: https://plt.simaat.sa/_layout/sound/piece-of-cake-611.mp3

But the script is failing with the following message:

choose:
  - conditions:
      - condition: template
        value_template: '{{ (message | string | trim) == '''' }}'
    sequence:
      - stop: Please provide a message.
