Generated node server fails with: "Cannot resolve the configured swagger-router handler:"

Description

Node server stub generated from Swagger 2.0 specification starts up fine, but throws an error on sending the request.

Here is the error log:

Looks like a dependency is broken. Not sure what though.

Reproduce the failure by generating a Nodejs-server stub from the linked Swagger declaration, starting it with npm start, and requesting /transactions/123. Inspect the generated route and handler name alongside swagger-router's handler resolution; done means the request no longer reports that the configured handler cannot be resolved.
