Dynamic Scheduling / Calendar widget error "The action parameter ids must align with the ids of the selected properties"

I’m trying to setup the Dynamic Scheduling / Calendar widget in Workshop, but I hit the below error:

 Invalid Configuration
 The action parameter ids must align with the ids of the selected properties

What am I doing wrong ?

The parameter ids in your action might not exactly match the property ids (names) of the start and end time properties you set up for the Calendar widget.In the action’s form - you should check the parameter details for your start and end timestamp parameters.

Can you check:

  • if your property is start_time, the parameter id must also be start_time
  • The type classes (e.g., schedules and schedules) are set on the properties and the action parameters (both !)

There might be ways to regenerate the action itself from the action too.
