Clojurians Log v2

Greetings! I ran the generator recently and am running into an exception : Missing definitions for refs: :duct.handler.static/not-found, :duct.handler.static/method-not-allowed, :duct.handler.static/bad-request, :duct.handler.static/bad-request, :duct.handler.static/bad-request, :duct.handler.static/bad-request. This happens when trying to start the system using (go) in the REPL. Looks to be originating from the following line in config.edn : :duct.router/ataraxy {:routes {[:get "/example"] [:backend.handler/example]}}. Did I miss something obvious or is this issue-material ?
