InvalidTemplate. The template language function ‘addDays’ expect a timestamp as the first parameter

Solution

Modified le 'addDays(utcNow(),10,'yyyy-MM-dd')'

There are two issues with the filter query expression. First, the expression should look like this:

addDays(utcNow(), 180, 'yyyy-MM-dd')

In addition, there need to be single quotes around the expression.
