Scheduled Report to get emails of the approvers

[Shree Nag]

Hello,

I have created with a report which has requested items that is pending approvals with approver info.

I have scheduled that report to be sent through email to all the approvers generated in the report. The script on the scheduled report is from this link.

I changed all "assigned_to" to "Approver". 

When I execute the scheduled report, no emails are generated. Please guide me what could be wrong

Attached the report and scheduled report script.

Script is schedule report:

answer = lookupUsersAndUpdateReport();

function lookupUsersAndUpdateReport(){

    // look up "assigned_to" people -- assumes "table" is task-based

    var senderArray = [];

    var PrevSender = '';

    var taskQueryGR = new GlideRecord(current.report.table);

    taskQueryGR.addEncodedQuery(current.report.filter);

    taskQueryGR.addEncodedQuery('assigned_toISNOTEMPTY');

    taskQueryGR.orderBy('assigned_to');

    taskQueryGR.query();

    while (taskQueryGR.next()){

        if (PrevSender != taskQueryGR.assigned_to + ''){ //filters out duplicate assignees

            senderArray.push(taskQueryGR.assigned_to + '');

            PrevSender = taskQueryGR.assigned_to + '';

        }

    }

    current.user_list = senderArray.join(',');

    current.setWorkflow(false);

    current.update();

    current.setWorkflow(true);

    // only return true if there were records listed in the result set

    if (senderArray.length > 0){

        return true;

    }

    return false;

}
