You only have one commit incorrectly signed off! To fix, first ensure you have a local copy of your branch by [checking out the pull request locally via command line](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/checking-out-pull-requests-locally). Next, head to your local branch and run: ```bash git commit --amend --no-edit --signoff ``` Now your commits will have your sign off. Next run ```bash git push --force-with-lease origin backend-interface ``` Commit sha: [7da3b63](https://github.com/databricks/databricks-sql-python/pull/573/commits/7da3b637fe250d0a1023609b247fb3b9d50efb9b), Author: varun-edachali-dbx, Committer: varun-edachali-dbx; The sign-off is missing.
