I have 2 fields Due date and Modified Due date. I want to get the difference between these two dates in days.
I tried the following formula:
{{[issue.Due date.diff(issue.Modified Due date).days}}Then I tried even the Field ID:
{{[issue.Due date.diff(issue.customfield_10837).days}}
But that still does not work, The rule runs successfully but the field Lag time is never updated with value.
