GlideAjax response returns null on client script

[venkatsaladi]

Hey Community, I wrote a client script for my catalog item, which automatically fills the manager name based on requestor id, so that I created script include but in client script glide ajax when logging response it returns null, could you please help.
I am sharing my code here.

var test_script = Class.create();
test_script.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    getName: function() {
        var managerName="";
        var managerID = this.getParameter("sysparm_managerid");
        var usr = new GlideRecord("sys_user");
        usr.addQuery('sys_id', managerID);
        usr.query();
        if(usr.next()) {
            var username= usr.getDisplayValue("user_name");
			managerName=username;
        }
        return managerName;
    },
    type: 'test_script'
});

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    g_form.getReference("requested_for", function(ref) {
        if (ref.manager == ""||!ref) {
            g_form.setDisplay("manager_name", false);
        } else {
            var ag = new GlideAjax('test_script');
            ag.addParam("sysparm_name", 'getName');
            ag.addParam("sysparm_managerid", ref.manager);
            ag.getXMLAnswer(function(response) {
				console.log(response);
            g_form.setValue("manager_name",response);
            g_form.setDisplay("manager_name",true);
            });
            
        }
    });
    //Type appropriate comment here, and begin script below

}

GlideAjax is an alternative to getReference when you want to do more than a simple lookup, so don't use both. You would want to send the GA parameter of requesrted_for, not the manager, but before we go any further correcting these scripts, have you tried the variable Auto-Populate feature instead of scripts in this case?

var test_script = Class.create();
test_script.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    // New method to get the manager name based on the requested_for user's sys_id
    getManagerName: function() {
        var managerName = "";
        var requestedForID = this.getParameter("sysparm_requested_for_id");

        if (requestedForID) {
            // First, get the 'requested_for' user record
            var userGR = new GlideRecord('sys_user');
            if (userGR.get(requestedForID)) {
                // Now, check if the user has a manager
                var managerID = userGR.getValue('manager');
                if (managerID) {
                    // Finally, get the manager's record to retrieve their name
                    var managerGR = new GlideRecord('sys_user');
                    if (managerGR.get(managerID)) {
                        managerName = managerGR.getValue('name');
                    }
                }
            }
        }
        return managerName;
    },
    type: 'test_script'
});

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        // Clear the manager name field and hide it if the requested_for field is empty
        g_form.setValue("manager_name", "");
        g_form.setDisplay("manager_name", false);
        return;
    }

    // newValue holds the sys_id of the 'requested_for' user
    var requestedForID = newValue;

    // Use GlideAjax to get the manager's name directly from the server
    var ga = new GlideAjax('test_script');
    ga.addParam("sysparm_name", 'getManagerName');
    ga.addParam("sysparm_requested_for_id", requestedForID);

    ga.getXMLAnswer(function(response) {
        // The 'response' is the manager's name returned from the Script Include
        if (response) {
            console.log("Manager Name received: " + response);
            g_form.setValue("manager_name", response);
            g_form.setDisplay("manager_name", true);
        } else {
            // If no manager is found, clear the field and hide it
            g_form.setValue("manager_name", "");
            g_form.setDisplay("manager_name", false);
        }
    });
}
