Service portal:

var sampleUtils = Class.create();
sampleUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getUserInfo: function() {
        // Log the incoming parameter
        var userId = this.getParameter('sysparm_userId');
        if (!userId) {
            gs.error('No userId provided');
            return JSON.stringify({ error: 'Invalid or missing userId' });
        }
        var gr = new GlideRecord('sys_user');
        gr.addQuery('sys_id', userId);
        gr.query();

        var jsonObj = {};
        if (gr.next()) {
            // Extract and log the values
            jsonObj.title = gr.getDisplayValue('title');
            jsonObj.manager = gr.getDisplayValue('manager');
            jsonObj.department = gr.getDisplayValue('department');
            jsonObj.location = gr.getDisplayValue('location');

        } else {
            gs.error('User not found with sys_id: ' + userId);
            return JSON.stringify({ error: 'User not found' });
        }

        // Return the user details as JSON
        return JSON.stringify(jsonObj);
    },

    type: 'sampleUtils'
});

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var userSysId = g_form.getValue('employee');
   
    if (userSysId) {
        var ga = new GlideAjax('global.sampleUtils ');
        ga.addParam('sysparm_name', 'getUserInfo');
        ga.addParam('sysparm_userId', userSysId);
        ga.getXML(callback);
    }

    function callback(response) {

        var answer = response.responseXML.documentElement.getAttribute("answer");
        var returneddata = JSON.parse(answer);
        g_form.setValue("employee_title", returneddata.title);
        g_form.setValue("employee_department", returneddata.department );
        g_form.setValue("employee_manager", returneddata.manager);
        g_form.setValue("employee_location", returneddata.location);
    }
