Redirect Via UI Script

[Rosy14]

Under Service Portal->Theme -> JS Include -> UI Script I added the below script to redirect.

The redirect is working but the if condition (to check role and field value) are not working.

(function() {

    var role = gs.hasRole("snc_internal");
    var user = gs.getUser();
    var userGr = user.getRecord();
    if (role && (userGr.getValue("u_user_type") == "Guest") && (!userGr.getValue("u_org_id"))) {
        var url = "https:test/supplier?id=kb_article_view&sysparm_article=KB0034151";

        window.location.assign(url);
    }

})();

tried this one also 

(function() {
function checkUserRole() {
var ga = new GlideAjax('UserRoleCheck');
ga.addParam('sysparm_name', 'checkUserRole');
ga.addParam('sysparm_role', 'snc_internal');
ga.getXMLAnswer(function(response) {
if (response === 'true') {
var url = 'https://supplierportal.asda.uk/supplier?id=kb_article_view&sysparm_article=KB0034151';
window.location.assign(url);
}
});
}

// Run the function when the script loads
checkUserRole();
})();

SCRIPT INclude

var RoleCheck = Class.create();

RoleCheck.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    hasRole: function() {

        var role = this.getParameter('sysparm_role');

        return gs.hasRole(role) ? 'true' : 'false';

    }

});
