Calendar Event Doesnt Return Info When Click

[bigverm23]

What I would like to do is when a calendar event is clicked, return the attributes of the event (message, description, etc) and use those to generate a custom popup for additional info.

It's possible I'm doing something wrong, but when an event is clicked, this is what is returned...empty

WEEKPLANNER DEBUG CLICK: title="[[[ return event.message ]]]" description="[[[ return event.description ]]]" calendar="[[[ return event.entity_id ]]]"

alias: Debug WeekPlanner Click
mode: queued
fields:
message:
description: Event title
description:
description: Event description
calendar:
description: Calendar entity_id
sequence:

• data:
  message: >
  WEEKPLANNER DEBUG CLICK: title="{{ title }}" description="{{ description
  }}" calendar="{{ calendar }}"
  level: warning
  action: system_log.write
  description: ""
