Hi Kevin,

I'm not sure what your code actually does but at a glance, I think you're trying to setup some sort of issue linking in a listener.

The error you're looking for is in line 20 - 

Issue issue = event.issue

You need to declare the event type. Try the below:

def IssueEvent event = event
def issue = event.getIssue()

I recommend going through Scriptrunner's documentation for more information on how to build Listeners - https://scriptrunner.adaptavist.com/latest/jira/listeners.html#_custom_listeners

Trying to make a listener that catches the link created event and if it is a certain link type it populated the parent link field automatically

Was able to get past the error.  Thanks for the help

@Kevin Dalton  Can you please share with us how did you managed to get past the error?  

[DVK]

@Kevin Dalton Could you please share the code with us get the event as Issue
