Hi @shubhamverm3478 ,

In gs.eventQueue('event.name', 'current'); current is an object and not string.

so, query the knowledge table and pass the object in 2nd parameter.

Example:

var current = new GlideRecord('kb_knowledge');
current.addEncodedQuery("your_query");
current.query();
if (current.next())
{
gs.eventQueue('event.name', current,"","");
}

Check who the notification should send to? If none give your name and see if email getting triggered. Once updated in notification re run the full activity again on another KB article

Can you share the whom to send tab in the notification that is configured.
