Jose, Leaving aside shrinking the jar, you could try: - Structuring your application so it's easier to construct plausible inputs in the tests / REPL - Using https://github.com/lambci/docker-lambda locally, to get an environment closer to the deployment target - Deploying to a geographically closer region, or triggering deployments on a build slave with better network connectivity - Deploying manually with awscli, as your package is small enough to be uploaded directly to lambda, rather than using S3
(With a strong bias for the first one - even if the your package was a third of the size, it's still going to be frustrating to deploy it and then get unexpected errors) Take care, Moe On Thu, Jul 20, 2017 at 5:16 AM, Jose Trigueros <j.v.trigue...@gmail.com> wrote: > Hi all, > > I've been using AWS Lambda for a small project.
