CLA Rescan Returns 400

[mattalbr]

I'm trying to send out #687 for review as my employer recently covered me with a CLA. When I launch the CLA rescan flow though, I get a 400.

https://cla.developers.google.com/github/rescan?pr=GoogleCloudPlatform%2fcloud-builders-community%2fpull%2f679&key=%01%40%a0%1f%11e%c0%0e%c1%ad%b9%f9%7d%b6S-%9dwl%0cG&expiry=2025-03-01

Sadly I don't see an extra information other than the 400 error code.
