Need autoboost help - copying end date of timeline to a date column

Using Autoboost and trying to set Due Date to the last date of the timeline when it changes.

When Timeline changes, apply formula and set results to Due Date
Formula = {task’s Timeline}#END

it runs and says looks like something is wrong with the formula.
