[keycloak-user] updateToken method not working

I use the following code to make sure I have a valid token before making a request. Even though I am logged in, if I wait until the token expires then make a request, the error function is called most of the time when I try to update the token using the updateToken method. I have the page reload, and I have a valid token again. However, I did not have to log in again because the session had not expired. I am using 1.1.0-Alpha1-SNAPSHOT I have read the documentation. Am I missing something? keycloak.updateToken().success(function() { if (data) { $http({ url: 'http://localhost:8080' + url, method: method, data: data, headers: { 'Content-Type': contentType, 'Accept': acceptType, 'Authorization': 'Bearer ' + service.auth.token }, transformRequest: angular.identity }).success(success).error(error); } else { $http({ url: 'http://localhost:8080' + url, method: method, headers: { 'Content-Type': contentType, 'Accept': acceptType, 'Authorization': 'Bearer ' + service.auth.token } }).success(success).error(error); } }).error(function() { alert("Token could not be refreshed!"); location.reload(); });
