Hi Moe, Thanks for your suggestions, yes, I've been mostly practicing the first option suggested. docker-lambda is a good option as well. It does help that Lambda provides test messages, which is what I've been using to test locally. Seems like the best way to go about it is to test as much as possible locally before uploading.
