@rahulgrover99 Could you please update the branch and fix the CI issues?

[rahulgrover99]

@gauravgahlot I was going through the checks that failed. It looks like the lint check failed because of the use of deprecated packages in db/template.go. Will it be a good idea to add nolint:staticcheck to those imports?
Also, another fail is because of no test coverage of the changes I made. Could you help me out with that as well? I am not sure what tests might help cover these changes.
