No handler signature, no event object, no Lambda Web Adapter layer. The same day, CloudFront added Web Functions as an origin type with origin access control. The functions you already have are now called <strong>Lambda Event Functions</strong>; that is a rename only and needs no code change. This guide walks through a first deployment with the new <code>aws lambda-web</code> CLI, the one environment variable your server has to honour, how to put the endpoint behind CloudFront without leaving a public back door, and the errors you are most likely to hit on day one.</p>
