I am getting the following error:

The error message is pointing to the following function:

Hello Terry,

Have you added functions.js asset to the project?
If so - it has some errors. Please check this file code with JSLint.
http://jslint.com/

There is an error with JSLint, it seems not to like the equals sign in duration = 3000.
However this is just a default setting.

this app works as a web app and will also build in debug mode, but not in release mode

It appears that the builder doesn't support Javascript ES6.
I change the code to the following (compatible with previous versions of Javascript):

pre /**

• Echo Error Message on service failure
  */
  function alertError(msg, duration) {
  duration = typeof duration !== 'undefined' ? duration : 3000;
  var el = document.createElement("div");
  el.setAttribute("style", "position:fixed; top:10%; left:10%; border: black 1px solid; background-color:white; color:red; width:80%; text-align: center; z-index: 1000;");
  el.innerHTML = "
  " + msg + "
  ";
  setTimeout(function(){
  el.parentNode.removeChild(el);
  },duration);
  document.body.appendChild(el);
  }/pre

Hello Terry,

Yes, you are absolutely right. Appery.io works with ES5 and doesn't support ES6
