How can I refer different object in

I am trying to generate Go code using openapi-codegen to generate the Go code. I have four different objects with different fields and based on the endPoint I want to set up the required object in the request body but for some reason my type file is coming as empty. Can someone please tell me where am I making mistake? or how can I refer my link everything together so I don't have to define the same objects for different endPoints?
