Hi Deepak,
with a stack trace like that it sure is a scary error message! But the reason for the “operation failed” could be as simple as that the tracker cannot detect your eyes. Have you checked out the eye tracker mounting guidelines?
A related cause could be that the display area isn’t set up correctly, because that can lead to inferior tracking.
