TL;DR: you need to create a map before you can set nested properties of that map Lately I have been working on a site analytics service in response to one of my recent posts. ( I am also streaming everything as I go if you want to follow along.) I…

This post is meant to be an openly published question to AWS. Why do Synthetics Canaries cost so much? As of this writing, the free tier includes 100 canary runs per month, but after that, I would have to pay $0.0012 per canary run. Let’s say I want to monitor…
