ACS - What is working and what is not?

Hello,

I am trying to develop a iOS app based on ACS but there is a lot of problem. I got the photo upload solved (custom sizes) but I am constantly running into problems with other endpoints (not all).

For example. Now I need to query events created on my ACS but I get this error:

{
    line = 78;
    message = "'undefined' is not an object (evaluating 'Cloud.Events.query')";
    name = TypeError;
    sourceId = 167196672;
}

This is how I use it:

Cloud.Events.query ({
 
   user_id: Ti.App.Properties.getString('user_id')
 
}, function (e) {

I am using the 2.0.5 version of Ci.cloud.js.

Thankful for all help!
