unable to access jsx file from java script in adobe photoshop

If all went fine when it was Illustrator only and then just fails because you open it to Photoshop, I would certainly check the jsx file.

An easy way is to run jsx file in ExtendScript ToolKit while Targeting Photoshop. If there is an execution error, you will quickly see.

what files do you need to verify?

i Did all the ways to trace the error and finally unable to find it.

It might be (hard to state without code) that Photoshop script engine evaluates code designed for illustrator (i.e. calling AI API such as app.activeDocument.artboards[0] ) — or the contrary — and fails to load, thus failing the data to be returned, thus leading to HTML/JS error.

Look at samples, they are designed to load and evaluate jsx files on a per app basis avoiding those kind of issues.

An easy way to debug is to comment all your jsx code once to see if problem still occurs and uncomment little by little until you find the problematic area of your code.
