No way to set action input with default option?

Hi! I made a blueprint where the user selects an action to be excecuted on trigger.
I added a default because the automation can’t be saved if you choose to not have an action for a sequence. But now I can’t select an action in ui? Edit: I added another input without default and I can choose an action in this input

blueprint:
  domain: automation
  input:
    shortcut_action1:
      name: Shortcut 1 action
      selector:
        action:
    shortcut_action2:
      name: Shortcut 2 action
      selector:
        action:
      default:
        stop: no button pressed
trigger:
condition: []
action:
  - choose:
      - conditions:
          - condition: trigger
            id: #IDofTrigger
        sequence: !input shortcut_action1
      - conditions:
          - condition: trigger
            id: #IDofTrigger
        sequence: !input shortcut_action2
mode: single

Can anyone help me out? Thanks!

A blank action will not cause an error, it will simply ececure nothing when it sees it in the execution. So I would just remove the default in the input section.
Then in the variables section, I would look at it and if it’s empty, plug your default in there. If there is a value then use the value…
