restapi/configure_todo_list.go - api.TodoGetHandler undefined error

[albertleng]

I am a newbie in go and go-swagger. I am following steps in Simple Server tutorial in goswagger.io.

I am using Ubuntu 18.04, swagger v0.25.0 and go 1.15.6.

1. Following the same steps, there are a few differences of the files generated. For instance, goswagger.io's has find_todos_okbody.go and get_okbody.go in models but mine does not. Why is that so?
   Mine:
   
   goswagger.io's
   

2. Starting the server as written in the tutorial go install ./cmd/todo-list-server/ gives me the following error. Can anyone please help with this?

# my_folder/swagger-todo-list/restapi
restapi/configure_todo_list.go:41:8: api.TodosGetHandler undefined (type *operations.TodoListAPI has no field or method TodosGetHandler)
restapi/configure_todo_list.go:42:6: api.TodosGetHandler undefined (type *operations.TodoListAPI has no field or method TodosGetHandler)

Thanks.
