Hi @aksinghdce

Thanks a lot for the fix and the pull request!

Couple of points to note:

Can you replace the XXXX in the PR description with the issue no 9481.

Closes currently open issue (replace XXXX with an issue no): Closes #9481

This will auto close the issue when this PR is accepted. Also next time do not mention the issue no in the branch name, rather have a short name like fix/challenge-name

@raisedadead
I noted your comments and changed the description.
Next time I will use appropriate branch name.

Thanks
