I saw this come up on /r/aws a few days back.

This response seemed illuminating:

> Looking at (this section)[https://will-o.co/gf4St6hrhY.png], it seems like you're trying to queue up an asyncronous task and then return a response. But when a Lambda handler returns a response, that's the end of execution. You can't return an HTTP response and then do more work after that in the same execution; it's just not a capability of the platform. This is documented behavior: "Your function runs until the handler returns a response, exits, or times out". After you return the object with the message, execution will immediately stop even if other tasks had been queued up.

If this is the case (it might very well be) I do at least find it odd that no one on AWS' side was able to explain this to them.

Based on the way the document is written, it seems very likely that several people did realize exactly what the misunderstanding was and try to explain it to them.
