Prasad,

When I switched the code to use the CDN urls for the esri JS API instead of your local install. The code worked fine.

You usually get this error when a html response is returned when, a json response is expected. Check the request and response in the Network tab and see if it gives a clue what's going wrong.

Prasad,

I cannot give you a solution, without knowing what the problem is.

All I am saying is the "Unexpected token < ..." error occurs when the server returns html instead or JSON. The "<" is not a valid in JSON, but it is used in HTML to begin a tag. The html can be anything from 'server not found' 404 or 'service unavailable' 503 etc.

You need to open the browser's developer window and look through all the requests sent, as well as response received. See if it contains any HTML response out of the ordinary. That will give is a clue what might be the cause of the problem.

Hope this was helpful.
