title: With AWS API Gateway and Lambda, i'm seeing the paths all prefixed with $default
body: <p>I'm using AWS API Gateway and Lambda</p>
  <p>Configuration is as follows:</p>
  <p>API Gateway: Protocol is HTTP, route is '$default', integration is to my lambda function, payload format is 1.0, and permissions are correctly configured, stage name is $default. Everything else is vanilla.</p>
  <p>Lambda: Runtime is 'custom runtime' (not linux 2), with an executable called 'bootstrap'. It's actually written in Rust using Rocket + rocket_lamb but that shouldn't make much difference.</p>
  <p>What i'm finding is that when you browse to the API Gateway Invoke URL, the lambda is called with path = '$default/' instead of '/' - eg it literally includes '$default'.</p>
  <p>Am i missing something here? Where is this $default coming from? I thought using '$default' in the route was the wildcard?</p>
  <p>Thanks</p>
