Should return 404 when path is not supported

[sebsto]

When deploying an application that handle /myroute/{my_Params} and invoking it with GET /, it returns an HTTP 500 instead of an HTTP 404 error.

Example

openapi.yaml :

paths:
  /stocks/{symbol}:
    get:

curl -v https://mwad60wxk9.execute-api.eu-west-3.amazonaws.com/
* Host mwad60wxk9.execute-api.eu-west-3.amazonaws.com:443 was resolved.
... (redacted for brevity) ...
> GET / HTTP/2
> Host: mwad60wxk9.execute-api.eu-west-3.amazonaws.com
> User-Agent: curl/8.6.0
> Accept: */*
>
