Task Checklist Observer notification and due date

[Jeff_Brown]

What field(s) drive(s) the calculation of the "must be completed by" date in the notification sent to the requested Task Checklist observer?

*************SYSTEM GENERATED EMAIL- DO NOT RESPOND****************

You have been sent a Task Checklist observation request for Demo Test Task Checklist (TEST_TSKCHKLST) for the User JaneDoe. This observation must be completed by: < /div>

If you have any questions please contact your learning coordinator.

This notification is the ObserverNotification in Notification Templates. Its content is as follows:

You have been sent a Task Checklist observation request for <ITEM_TITLE/> (<ITEM_ID/>) for the User <FIRST_NAME/> <LAST_NAME/>. This observation must be completed by: <REQ_DATE/>

but even if the typical fields for calculating a required date are populated, I'm getting an error here, presumably because requesting someone as an observer is not enough to trigger calculation of a Required Date as assigning the training would do.
