Update method not working in Scheduled Job

[surbhi_123]

I have a scheduled job written as -

(function(){

    var appSer=new GlideRecord('cmdb_ci_app_server');

    appSer.addEncodedQuery('sys_idISNOTEMPTY');

    appSer.query();

    while(appSer.next()){

    gs.log("sj run");

    //var sysId =appSer.sys_id;

    var gr = new GlideRecord('cmdb_rel_ci');

    var sysId = 'b25bb2c7db38abc076b9ee71ca9619a5';

    gr.addEncodedQuery('parent.sys_class_name=cmdb_ci_appl^child.sys_id='+sysId);

    gr.query();

    var arr = [];

    while (gr.next()) {

        var appSysID = gr.parent;

        gs.log("app sys id" + appSysID);

        var gp = new GlideRecord('cmdb_ci_appl');

        gp.addQuery('sys_id', appSysID);

        gp.query();

        while (gp.next()) {

            var x = gp.u_notice_domain.toString();

            gs.log("x val:"+x);

                x = x.split(',');

                for (var i = 0; i < x.length; i++) {

                    arr.push(x[i]);

                }

        }

    }

    gs.log("arr length:"+arr.length);

    var unique = [];

    var seen = {};

    for (i = 0; i < arr.length; i++) {

        var val = arr[i];

        if (!seen[val]) {

            seen[val] = true;

            unique.push(val);

        }

    }

    gs.log("set unique" + unique);

    appSer.u_notice_domain = unique.toString();

    appSer.update();

    }

})();

Here in logs value I am getting the unique value but it is not being set to the u_notice_field name.
