Script runner listener throwing unRegister Listener exception

[Ushma Mulwani]

Hi , 

I am new to script runner and trying to learn listener. 

I have created a simple in-built listener to print 'Hi' in my log file.

However, whenever I add any built-in listener I get Error: com.atlassian.event.internal.LockFreeEventPublisher.unregisterListener(java.lang.String) exception thrown. 

Is there any configuration I am missing to use Listener?

I checked few videos regarding the same though it didn't yield any results. 

Error: com.atlassian.event.internal.LockFreeEventPublisher.unregisterListener(java.lang.String)

You need to update your script runner app from your add-ons.
