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 feat/string-byte-array ``` Commit sha: [486741b](https://github.com/enarx/ciborium/pull/148/commits/486741b6bf48f64c290be49303b82c15b1c3929b), Author: Ibiyemi Abiodun, Committer: Nathaniel McCallum; The sign-off is missing.
