Shopping list notification not working properly

1

I’m using 2023.12.4

I created a Shopping List called ‘Shopping list’.
I created an automation that sends a notification to my phone when a new item is added to ‘Shopping list’.
This works well.

I created another list called ‘Household tasks’.
I created an automation that should send a notification to my phone when a new item is added to ‘Household tasks’.
This does not work.

This is the yaml that works

alias: Notify on new shopping list item
trigger:
  - platform: event
    event_type: shopping_list_updated
    event_data:
      action: add
action:
  - service: notify.mobile_app_rix_iphone1
    data:
      message: "{{ trigger.event.data.item.name }} has been added to the shopping list"
      data:
        clickAction: /shopping-list
        url: /shopping-list

This is the yaml that does not work. It looks the same to me.

alias: Notify on new Household task
trigger:
  - platform: event
    event_type: household_tasks_updated
    event_data:
      action: add
action:
  - service: notify.mobile_app_rix_iphone1
    data:
      message: "{{ trigger.event.data.item.name }} has been added to Household Tasks"
      data:
        clickAction: /household-tasks
        url: /household-tasks

When I look at ‘Traces’ I find
Error: Error rendering data template: UndefinedError: ‘dict object’ has no attribute ‘event’

I have tried double-quotes arouind the ‘action’, ‘clickAction’ and ‘url’ variables.

UPDATE: When I look in ‘Integrations’ I see that ‘Shopping list’ is one Integration and ‘Household tasks’ is an entity in a different Integration called ‘Local To-do’

Can any of you clever people tell me what I am doing wrong?
Thanks
