Generated nodejs-server from the above build.

      summary: config info.

Expected behaviour: XML is passed to the server and can be processed. undefined is received.

Reproduce the generated nodejs-server from the linked swagger-codegen build using the provided OpenAPI request definition and an application/xml POST. Trace the request-body handling from the generated server entry point; done when the XML payload reaches the server for processing instead of being received as undefined.
