Can {{input}} from a For Each task be used as a dashboard subscription destination_id

Hello everyone,

I am using a DAB to send a dashboard snapshots to notification destinations.

The intended design is to use a For each task for multiple team/destination pairs. As a minimal test, I am iterating over an array containing one notification destination ID:

variables:
  destination_1_nonprod:
    lookup:
      notification_destination: destination_1_nonprod

  team_subscriptions:
    description: JSON array of notification destination IDs
    default: '["${var.destination_1_nonprod}"]'

 

resources:
  jobs:
    job1:
      ...

      parameters:
        - name: team_subscriptions
          default: ${var.team_subscriptions}

      tasks:
        - task_key: send_team_reports
          for_each_task:
            inputs: "{{job.parameters.team_subscriptions}}"
            concurrency: 5

            task:
              task_key: send_team_report
              dashboard_task:
                dashboard_id: ${resources.dashboards.my_dashboard.id}
                warehouse_id: ${var.warehouse_id}
                subscription:
                  subscribers:
                    - destination_id: "{{input}}"

The bundle correctly resolves team_subscriptions to a JSON array containing the notification destination UUID and I can see that in the UI inside the task "job parameters".

The job succeeds but no notification is delivered, silently ignoring the issue.

As a control test, replacing the dynamic reference with the bundle lookup works correctly:

subscription:
  subscribers:
    - destination_id: ${var.destination_1_nonprod}

I also 

I also considered using a json object with key:value and iterating over it using:  

destination_id: "{{input.destination_id}}"

but it still silently fail the delivery 

 

 

Does dashboard_task.subscription.subscribers[].destination_id support Lakeflow dynamic value references such as {{input}} or {{input.destination_id}}?

If it does, what is the correct syntax or configuration?

Thank you for your attention
