Did some investigation to resolve the issue. Verified the "Task name", "Command for Full load" and "Incremental load for naming"...etc.

And finally got some clues to resolve the issue.

Solution: Remove the escape characters from the description of the objects( Either in folder,mapping or session...etc objects description).

If you see the workflow xml, description field values in not parsing correctly because of the " (extra double quotes".

 So you just make sure the description column should not contain any special characters and escape characters.

CHEERS :)
