KPI Notable events custom fields

[JPUser]

I have a KPI alert using adhoc search which outputs custom fields and then custom alert action is configured on Notable aggregation policies ( NEAP) action rules which trigger the action on KPI notable event . alert_actions.conf has all the params defined. But $results.fieldname$ is always blank on the script.  results_file only have ITSI /KPI specific fields but do not have the custom fields.  

How

Take a look into the index itsi_grouped_alerts and try to find your alert which should fire the alert action. Check if you can find the field you are referring to in this event and if there is content.
