Setup script selector / continue_on_error

Configuration
1

Hi,
I’ve some issues with script selector / continue_on_error (Home Assistant 2022.12.8).

  • script selector:
    At this point I will refer to the example at the script-documentation
    fields:
      minutes:
        name: Minutes
        description: "The amount of time to wait before turning on the living room lights"
        selector:
          number:
            min: 0
            max: 60
            step: 1
            unit_of_measurement: minutes
            mode: slider

What are the selector entries for? There is no slider; neither in entity-informations nor in a dasboard-elements-card. How do I send values as params to a script from a dashboard-card.

  • script continue on error
    The sample is from 
alias: new script
sequence:
  - alias: If this one fails...
    continue_on_error: true
    service: persistent_notification.creater
    data:
      message: I'm going to error out...
  - alias: This one will still run!
    service: persistent_notification.create
    data:
      title: Hi there!
      message: I'm fine...
mode: single

The script aborts with error message, no continue.

What am I doing wrong?

Thank you
