使用go-swagger生成swagger.json给我无法使用模型错误

I am quite new to Golang and have been trying to use go-swagger to generate REST API documents. I have been following

articles for implementing this. I used Gorrila Mux as a router in my application. But after annotating the code, when I try to generate the swagger.json file, I get a weird error showing something like this

cannot use &authModel (value of type *model.AuthLoginModel) as *model.AuthLoginModel value in argument to (service.AuthService literal).ValidateCredential

BackGround: I have created a struct called AuthLoginModel and put the annotation

//swagger:model

on top of the defined struct(which is in a different models package). In my file I am creating a variable of the type AuthLoginModel and and using it in my function called ValidateCredential as shown below.

var authLM model.AuthLoginModel
{populate authLM}
validateCredentials(&authLM, {other parameters})

My annotation on for my main.go is as shown below.

    // Package rest HTTP API.
    //
    // Schemes: http
    // Host: localhost
    // BasePath: /api
    // Version: 0.0.1
    // Consumes:
    // - application/json
    // Produces:
    // - application/json
    // swagger:meta
    package main

And my annotation for the handler is as shown below

// swagger:operation POST /token/generate Token_generate
// Generates a token
//
// ---
// summary: Token Generation
// parameters:
//  - in: body
//    required: true
//    schema:
//       $ref: "#/token/generate"
// responses:
// responses:
//  '200':
//   description: successful operation
//   schema:
//    $ref: "#../../model/AuthLoginModel"
//
