@balajiv113 thank you for providing a fix for the styling, do you mind reverting the unnecessary changes (formatting) since it adds noise to the pull-request and makes it more difficult to review. Else, you can group the formatting changes in a secondary commit 👍

@balajiv113 do you mind rebasing the pull-request on the latest master (it should resolve the build errors).
