Setting a relative due date with automation for jira

[Ben Cohen]

I would like to be able to set a due date based on another field value. I am able to use automation for jira OR JMWE to do this and can set the trigger, but have not been able to detemine the proper JSON needed to complete the task. If there is another way to do this that would also work as well, although trying to accomplish without having to build a listener. 

Goal:

Field X changes to "abcd" -> set due.date to (change.date + 14d)

Hi @Ben Cohen

I've done this with scriptrunner and with a listener. This could also be done with JA by setting a field value change.

Why, if i may ask, the solution you've come up with, doesn't suit your need?
