@loic-seguin Maybe the email associated with your github account is different from the email you signed the CLA with? Can you confirm?

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for the commit author(s). If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google.

CLAs look good, thanks!

Everything is ok with the CLA, I changed the email of the commiter.
