This payload seems to repeatedly trigger an error between MEFE & the Invite lambda.

I'm assuming it's some failure wrt to procedure the invite lambda calls with that payload, hence the bug report here.

Another concern is that we don't have a way of saying this message was tried XYZ amount of times, and it's obviously something seriously wrong with it. Aka the poison pill problem in microservices. I noticed it because I monitor AWS/Lambda Errors across all functions.

I think if unee-t/frontend#797 was dealt with, this problem would go away, because then there would be a clear request and error response for @nbiton's MEFE to act on.
