Issue with Script Include - Unhandled exception in GlideAjax

[Community Alums]

I think I am pretty close with this, but getting error Unhandled exception in GlideAjax

I am creating MRVS, when asset is selected I need to populate the assigned_to for the asset.

My script includes

var FindAssetAssignedTo = Class.create();

FindAssetAssignedToHardware.prototype = Object.extendsObject(AbstractAjaxProcessor, {

getSupportGrp: function()

{

var asgnTo=this.getParameter('syspam_assigned_to_sysid');

var getAsgnTo=new GlideRecord('alm_hardware');

getAsgnTo.addQuery('sys_id',asgnTo);

getAsgnTo.query();

while(getAsgnTo.next()) {

var json = new JSON();

var object = {

"assignedto" : getAsgnTo.getValue("assigned_to"),

};

var data = json.encode(object);

return data;

}

},

type: 'FindAssetAssignedToHardware'

});

-----------------------------------------------------------------

My onChange client script

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

if (isLoading || newValue === '') {

return;

}

//Type appropriate comment here, and begin script below

var ga= new GlideAjax('FindAssetAssignedToHardware');

ga.addParam('sysparm_name','getSupportGrp');

ga.addParam('syspam_assigned_to_sysid',newValue);

ga.getXML(FindAssetAssignedToHardwareParse);

function FindAssetAssignedToHardwareParse(response) {

var answer = response.responseXML.documentElement.getAttribute("answer");

//var returneddata = answer.evalJSON(true);

var returneddata = JSON.parse(answer);

g_form.setValue('assigned_to' , returneddata.assignedto);

}}

-----------------------------------------------------

Any ideas?

Hi @Community Alums ,

Can you try this below script & check

Script Include:

var FindAssetAssignedTo = Class.create();
FindAssetAssignedTo.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    getSupportGrp: function() {
        var asgnTo = this.getParameter('syspam_assigned_to_sysid');
        var getAsgnTo = new GlideRecord('alm_hardware');
        getAsgnTo.addQuery('sys_id', asgnTo);
        getAsgnTo.query();

        if (getAsgnTo.next()) {
            var data = getAsgnTo.assigned_to.toString();
            return data;
        }
    },

    type: 'FindAssetAssignedTo'
});

Client Script:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
//Type appropriate comment here, and begin script below
var ga= new GlideAjax('FindAssetAssignedToHardware');
ga.addParam('sysparm_name','getSupportGrp');
ga.addParam('syspam_assigned_to_sysid',newValue);
 
ga.getXML(FindAssetAssignedToHardwareParse);
 
function FindAssetAssignedToHardwareParse(response) {
 
var answer = response.responseXML.documentElement.getAttribute("answer");
 
g_form.setValue('assigned_to' , answer);
}}

Thanks,

Danish

Hi @Community Alums 

Can you try replacing,

var data = json.encode(object);

with

var data = JSON.stringify(object);

In your client Callable script include.

Please mark my answer helpful and accept as solution if it helped you 👍✅

Hi @Community Alums 

Let's try this cool feature without single line of code. => Auto-populate

Cheers,

Excellent, I knew about this for regular variables, but missed that it is an option with MRVS.
