Using listeners for issueWatcherDeletedEvent

Question

Hi, I'm trying to create a listener which will send an email when the number of watchers goes to zero. While I can get it to work in the Preview, when I go live with it, I get an error:

2020-05-07 13:41:26,074 ERROR [runner.AbstractScriptListener]: *************************************************************************************
2020-05-07 13:41:26,074 ERROR [runner.AbstractScriptListener]: Script function failed on event: com.atlassian.jira.event.issue.IssueWatcherDeletedEvent, script: com.onresolve.scriptrunner.canned.jira.workflow.postfunctions.SendCustomEmail
org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'com.atlassian.jira.event.issue.IssueWatcherDeletedEvent@177e124f' with class 'com.atlassian.jira.event.issue.IssueWatcherDeletedEvent' to class 'com.atlassian.jira.event.issue.IssueEvent'

This happens even if I comment out all the script, so it appears to be an issue with the event itself. Any thoughts or ideas for what I could try?

Hi - yes - thats basically what I did by creating the second one. I'm going to have a look at the release notes to see if there is anything there. We are on 7.13 so there hae been a few fixes since then.

Hi @Alan Price

It looks fine to me so you might be right about a possible bug.

Have you tried to delete the listener and then create it from scratch again?

Ok here it is - but as you can see the script is commented out. This is the 'send custom email' listener but I also tried the same event in 'fires an event when condition is true' and that does the same - I think this is a Jira bug.
