Note: Need to do changes to make your code look good.

Hi I'm currently working on an application which is developed in HTML5, so automating the drag and drops functionality has been a nightmare. I found your work to be really helpful. When implemented the code in my local test framework, I'm facing this error "TypeError: Object of type WalkthroughClient is not JSON serializable"

I have not include the drag_drop.js in the project folder. Is it because of this ?? If not please give me steps to implement

Hope below implementation steps by me helps you...:) happy coding

Were anyone able to drag and drop in this site with above piece od code?
