Load CEP from javascript file

I'm running a javascript file from apple script.

I would like to load CEP from the js file.  Here is what I'm attempting to do but it's not working.  I'm getting this error:

Adobe Illustrator got an error: Error 2: window is undefined.

First I load my js file in illustrator like so:

set jsFilePath to POSIX file "/Library/Application Support/Adobe/CEP/extensions/CEP_HTML_Test_Extension-9.0/js/autoRunTemplates.js"

tell application "Adobe Illustrator"
	launch
	do javascript jsFilePath
end tell

 Then I attempt to load the CEP file.  (Normally I load this in html).

function runScript() {
  #include './CSInterface.js'
}

runScript();

My goal is to run a javascript file from apple script to run some CEP type scripting in illustrator.
