Event got triggered but notification not triggered

Hi All,

I need to trigger the notification from flow design using the event, in the event only i need to define the group dynamically.

below script works in event log it shows user sys id in Param 1 but notification not triggered.

var grp = current.getValue('reslovergroup'); 
var arr = [];

var gr = new GlideRecord('sys_user_grmember');
gr.addQuery('group', grp);
gr.query();
while (gr.next()) {
arr.push(gr.getValue('user'));
}

// gs.eventQueue parameters: eventName, GlideRecord, parm1, parm2
// You cannot pass an array directly. You must either loop or join it.

for (var i = 0; i < arr.length; i++) {
gs.eventQueue('your.event.name', current, arr[i], '');
}

Please suggest
