@stefanmcshane Great! Thanks for fixing this. Unfortunately, I'm unable to merge it until the CLA is signed. I know this is a trivial change but it is a required check in this repository. But, fortunately, it's a one-time process for all HashiCorp repositories. If your employer prohibits or if you decide not to sign it, please close the PR and that will signal to me that I need to rewrite your change on my own.
