undefined is not an object error is coming in jsx file with In-design Extended script tool kit
I am begineer in-design and trying to explore this tool for my project needs. I come to know that extended script tool is good to get started with in-design scripting but when I tried a simple jsx file for document creation I am getting following bug "undefined is not an object". If there is any references we need to give of any files/libraries to make it working.

Please help
