Hey Shawn, never did figure this out. In the end I decided to move to a serverless.yml for other reasons, primarily the lack of examples as I couldn’t get binary files being moved between api gateway and my lambda functions correctly.
Haven’t thought about building and deploying for a few months now, but out our product live this week so automating this is now back to the top of my list. I hope having moved to a yml file it will make it easier.
