Thank you for your pull request and welcome to our community. We could not parse the GitHub identity of the following contributors: Jacob.
This is most likely caused by a git client misconfiguration; please make sure to:

1. check if your git client is configured with an email to sign commits git config --list | grep email
2. If not, set it up using git config --global user.email email@example.com
3. Make sure that the git commit email is configured in your GitHub account settings, see https://github.com/settings/emails

Is there no way to verify CLA without requiring contributors to expose private email address? I have github configured to "Block command line pushes that expose my email."

[msarahan]

confirmed CLA. You're good. It's a part-manual process. I had to manually add your name to the special list.

whatever. Just ignore it. I'll wait on CI here, but I think your change is fine.

[msarahan]

There are a few failures on master with the output from conda run. Those are not related to your change here and are OK to ignore.

Thanks @jhultman
