Hello @vinayakkulkarni,
Although your PR seems correct, I don't think it will fix your issue.
That's just a warning, but the real error that stopped your release process was:

RequestError [HttpError]: Review cannot be requested from pull request author.

You're assigning yourself as a reviewer and GitHub doesn't allow it. That's why it failed.

Feel free to reopen if needed :)
