Getting "[object Object] - undefined - undefined" as output in the desired field

[Community Alums]

Hi All,

I have written script to fetch data from script include but in desired field getting output as "[object Object] - undefined - undefined". what would be the mistake?. PFB output screenshot, script include and client script respectively.

Script Include - 

IsEscalate: function() {
        gs.log("enter into 6 line");
        var task1 = this.getParameter('sysparm_oas');//.toString();
        var scTask = new GlideRecord('sc_task');
        scTask.addQuery('request_item', task1);
        //scTask.addQuery('state', 1);
        //scTask.addQuery('stateIN-5,1,2');
        scTask.query();
        var arr =[];
        
        gs.log("Enter into line 11");
        while (scTask.next()) {
            var obj = {};
            gs.log("enter into 12 line");
            obj.agm = scTask.getDisplayValue('assignment_group.manager').toString();
            obj.ag = scTask.getDisplayValue('assignment_group').toString();
            obj.scn = scTask.number.toString();
            arr.push(obj);
            gs.log("Hello");
        }
        gs.log("enter into 20 line");
        var data = JSON.stringify(arr);
        gs.log("enter into 23 line");
        gs.log("Test"+obj);
        return data;
        //gs.log("Hi");
        },

Client Script - 

function onSubmit() {
    var a = g_form.getUniqueValue();
    var ga = new GlideAjax('EscalatedScTask');
    ga.addParam('sysparm_name', 'IsEscalate');
    ga.addParam('sysparm_oas', a);
    ga.getXMLWait();
    alert('Sys id is ' + a);
    alert("line 7");
    var arr = JSON.parse(ga.getAnswer());
    alert("line 9");
    alert(arr);
    g_form.setValue('u_escalation_owner_assignment_group_sctask', arr[0] + " - " + arr[1] + " - " + arr[2]);
    alert("line 11");
}

i think the element are not getting pushed properly 

        obj.agm = scTask.assignment_group.manager.getDisplayValue();
            obj.ag = scTask.assignment_group.getDisplayValue().toString();
            obj.scn = scTask.number.toString();

try this in script include and let me know of the alert is coming properly

Same error and alert

[Mohith Devatte]

try returning the array itself like below 

        return JSON.stringify(arr);

Thanks Mohith,

It worked with

Script Include - 

IsEscalate: function() {
        var task1 = this.getParameter('sysparm_oas');//.toString();
        var scTask = new GlideRecord('sc_task');
        scTask.addQuery('request_item', task1);
        scTask.addEncodedQuery('stateIN-5,1,2');
        scTask.query();
        var arr =[];
        
        while (scTask.next()) {
            var obj = {};
            obj.agm = scTask.getDisplayValue('assignment_group.manager').toString();
            obj.ag = scTask.getDisplayValue('assignment_group').toString();
            obj.scn = scTask.number.toString();
            arr.push(obj);
         }

        return JSON.stringify(arr);
        
        },

Client Script - 

function onSubmit() {
    
    var a = g_form.getUniqueValue();
    var ga = new GlideAjax('EscalatedScTask');
    ga.addParam('sysparm_name', 'IsEscalate');
    ga.addParam('sysparm_oas', a);
    ga.getXMLWait();
    
    var arr = JSON.parse(ga.getAnswer());
    g_form.setValue('u_escalation_owner_assignment_group_sctask', arr[0].agm + " - " + arr[0].ag + " - " + arr[0].scn);
}

But one issue is if Multiple tasks are open on RITM the attached output we are getting (If one task is there it is working correct), what would be the issue?

The field details are 

String type with length 4000
