If a script (e.g. Post Function or Script Listener) fails to execute successfully, you can send a group email to notify those concerned. To do so, select the relevant Notifications Group from the drop down list.
The default value is the 'site-admins' group.
In addition to the group notification, you can also activate the Notify Assignee and Reporter option to send an email notification to the Assignee and Reporter of the failed script.
