Hi BDupont,
Indeed you have a path validation error.
I'm not familiar with Swagger but I think you are mingling here service uri and request path.
In your example, "testSwaggger" service uri is "/test". If you are sending an http get request to "http(s)://<pathToYourgateway>/test", the request path is empty, throwing an error with your swagger validation assertion.
Try to add a ressource to your service, let's say "movies". Now add this request path to your swagger description (just replace /test with /movies).
Change the service resolution path resolution logic from your service in order to accept this pattern (in service properties).
Request to http(s)://<pathToYourgateway>/test/movies must now match your new swagger description
Hope this helps !
