If you look at the commit message, it seems to have the proper line - is the automation confused because I used my real name there (instead of my github username)? The contributing guide does say "please use your real name" for that line.

I believe it's expecting your github user name:

Expected "alex-at-cascade alex.dommasch@cascadeenergy.com", but got "Alex Dommasch alex.dommasch@cascadeenergy.com".

But https://github.com/opensearch-project/opensearch-js/blob/main/CONTRIBUTING.md says very clearly:

Additionally, please use your real name. We do not accept anonymous contributors nor those utilizing pseudonyms.

Is that guide inaccurate? (I just want to do the right thing here.)

@alex-at-cascade Hey sorry for the late response. I was out the last few days.

You're correct. However the DCO is based off of your github info. In this case, your email address already reflects your name. You can also update your github account to your real name. The goal of the DCO is helping us identifying the contributor, and I think yours is satisfactory :)
