Need to check subtask's user

[Saira]

Hello!

I'm trying to implement a validation check in a workflow that prevents the person who is transitioning a subtask to be the same person as the reporter of the parent issue.

So basically the current logged in user should not be the parent issue's reporter. I use Jira cloud and trying to use scriptrunner to do this

currentUser != issue.getParentObject().getReporter()

This is not working, what am I doing wrong?

Hi @Saira maybe issue.getParentObject() can return null 
So issue.getParentObject().getReporter() can throw null pointer exception -> error

def parentTicket = issue.getParentObject()
parentTicket != null && (currentUser != parentTicket.getReporter())

or 

issue.isSubTask() && (currentUser != issue.getParentObject().getReporter())

Remember to publish your workflow before performing the test

Best regards,
