Thanks for your pull request. It looks like this may be your first contribution to a Google open source project (if not, look below for help). Before we can look at your pull request, you'll need to sign a Contributor License Agreement (CLA).

:memo: Please visit https://cla.developers.google.com/ to sign.

Once you've signed (or fixed any issues), please reply here (e.g. I signed it!) and we'll verify it.

What to do if you already signed the CLA

Individual signers

• It's possible we don't have your GitHub username or you're using a different email address on your commit. Check your existing CLA data and verify that your email is set on your git commits.

Corporate signers

• Your company has a Point of Contact who decides which employees are authorized to participate. Ask your POC to be added to the group of authorized contributors. If you don't know who your Point of Contact is, direct the Google project maintainer to go/cla#troubleshoot (Public version).
• The email used to register you as an authorized contributor must be the email used for the Git commit. Check your existing CLA data and verify that your email is set on your git commits.
• The email used to register you as an authorized contributor must also be attached to your GitHub account.

Thanks for fixing this! It's a simple enough fix and I can apply it in a number of ways.

However, in order to actually apply this PR my employer requires you or your organization to sign the CLA as referenced before.

I am not a lawyer and I cannot advise you on this. In general, this project is open sourced under the Apache 2.0 license. The purpose of the CLA is to ensure that you, too, promise to follow that license. I hope that makes sense. Thanks!

I had already signed it but forgot to reply here :-)
