I followed the steps from here: http://cocos.sonarlearning.co.uk/v1.0/docs/importing-a-scene-into-cocos

Still I get errors. JS: /data/data/org.cocos2dx.PrebuiltRuntimeJs/files/debugruntime/script/jsb_boot.js:768:TypeError: type is null

This is what I do:
1) I open Cocos Studio and create a new project.
2) I use “Login Demo” because I just want to test this whole thing first.
3) Once it is opened, I press CTRL + P (publish)
4) In the publish settings, the Data Format is set to JSON File since I use Cocos2d-js.
5) I copy the whole directory with its content that I just published (Default directory where all the checkbox images and fonts are, Login directory where the sprites are, and the json files that have been generated)
6) So I copy these into my project folder->res directory where all the images and resources are located.
6.5) I add the extra module “cocostudio” to the project.json file modules. 
7) In Cocos Code IDE I use the following code:

var rootNode = ccs.load("res/");
this.addChild(rootNode.node);

And I get the errors. What should ‘node’ be instead? What is going wrong? Either your tutorial isn’t really clear or I’m just too stupid for this stuff.
