Configuration
1

I have the following automation, which should be triggered by two ios actions.

alias: Garage - Open/close garage/gate via Apple Action
id: garage_apple_action
trigger:
  - id: garage
    platform: event
    event_type: ios.action_fired
    event_data:
      actionName: Garage
  - id: gate
    platform: event
    event_type: ios.action_fired
    event_data:
      actionName: Gate

condition: []

action:
  - choose:
      - conditions:
          - condition: trigger
            id: garage
        sequence:
          - service: cover.toggle
            entity_id: cover.garage
      - conditions:
          - condition: trigger
            id: gate
        sequence:
          - service: cover.toggle
            entity_id: cover.gate
    default: []

I noticed that it does open and close the gate correctly, but the garage is not triggered.
Checking the trace gave me the following error message:

Can someone spot an error in the automation?

I can’t offer any advice on your automation since it looks OK as far as I can see but strangely I just saw that same error for the first time today for one of my automations.

I’m not even aware of any way to share the trace with the developers.
