Swagger-codegen generated code having issues Routing requests with parameters in path

Description

I created my api definition using swagger and have generated the server code using Swagger-tools in NodeJs. The SwaggerRouter handles all routes properly excepts the routes with ID. For example , routes like

/v1/factoris/self 
/v1/factoris/create

are directed to the right controller but calls with IDs

/v1/factoris/{factoris_id}

are returned as invalid routes.

Any idea what I might be missing ?

Here is a sample of the swagger specs

Swagger-codegen version

Swagger 2.0
Swagger-editor - 2.10.4

Swagger declaration file content or url

Start by reproducing the request against the SwaggerRouter using the supplied Swagger 2.0 declaration, comparing the working static routes with /factoris/{factori-id}. Trace how the generated server routes path parameters to the Factoris controller and verify that requests with an ID reach the expected controller without breaking the existing routes.
