Hi. Yes, but I am confused about what name and email we can use for signing off... I did sign off the commit, but just with a different name and email. I used the same name and email for sign-off when contributing to other OpenSearch repos. I found out other OpenSearch repos only require all commits to be signed off but don't specify the name and the email has to be "@users.noreply.github.com". Do I need to change my local git config to that name and email?

can you check your email settings of github with link https://github.com/settings/emails, that should be the same one with signing off

I just checked, It is actually the same email but in my GitHub email setting, I enabled "Keep my email addresses private". Now I disabled it, also I changed my GitHub profile name to match the local git config. I think now it should be able to pass the DCO check... Is there a way to trigger the DCO check again?

can you try with following steps as suggested

1. Ensure you have a local copy of your branch by checking out the pull request locally via command line.
2. In your local branch, run: git rebase HEAD~1 --signoff
3. Force push your changes to overwrite the branch: git push --force-with-lease origin backport/backport-908-to-2.x

3. git push --force-with-lease origin backport/backport-908-to-2.x

I got this error

it's possible that I did not the check out pull request locally correctly, I am a little bit confused about "getting a local copy"
so what I did was:
I ran the git rebase HEAD~1 --signoff and git push --force-with-lease origin backport/backport-908-to-2.x commands

I am a little bit confused about "getting a local copy"

To get a local copy of this PR run gh pr checkout 912. However i am not sure you have permission to push changes to branch backport/backport-908-to-2.x directly and I have set DCO as passed manually this time.
