I had a similar issue - and it had nothing to do with the way that the API was configured or the POST request that I was making on the front-end. What fixed the problem for me was deploying the API on AWS API Gateway. Once you create an API method/resource, and tie them to a lambda function, they do not auto deploy.

You have to click "Actions" and then "Deploy API" in order to access these MicroServices from the front-end.
