LGTM, do you have a reference to the corresponding AWS Docs I can look at to verify? If not that's fine, just need to make some time to trigger the event myself :)

[chrispruitt]

I don't. The only docs I found on the codebuild notification event, were only example JSONs that didn't include this field. But I found that it exists when actually consuming codebuild notifications.

https://docs.aws.amazon.com/codebuild/latest/userguide/sample-build-notifications.html

[bmoffatt]

I was able to verify this by starting a build using the "Start build with overrides" flow in the console.
