[QUESTION][JAVASCRIPT] generated source differs from your example (How to use it)

Hi

I have got a small api and generate some code for it. I am figuring out how to use it.

From the examples I found this https://github.com/OpenAPITools/openapi-generator/blob/master/samples/client/petstore/javascript/docs/PetApi.md#addPet

So I have tried to apply this example for my api. But I don't get it working, nothing is send to the api server.

I have got this:

var Api = require('api')     
vae UserApi = new Api.UserApi()
var body = new Api.NewUserRequest()
body.name = 'test name'
body.email = 'test email'
UserApi.createUser(body, callback)

This is the generated UserApi:

import ApiClient from "../ApiClient";
import ErrorResponse from '../model/ErrorResponse';
import NewUserRequest from '../model/NewUserRequest';
import User from '../model/User';

/**
* User service.
* @module api/UserApi
* @version 1.0
*/
export default class UserApi {

    /**
    * Constructs a new UserApi. 
    * @alias module:api/UserApi
    * @class
    * @param {module:ApiClient} [apiClient] Optional API client implementation to use,
    * default to {@link module:ApiClient#instance} if unspecified.
    */
    constructor(apiClient) {
        this.apiClient = apiClient || ApiClient.instance;
    }


    /**
     * Callback function to receive the result of the createUser operation.
     * @callback module:api/UserApi~createUserCallback
     * @param {String} error Error message, if any.
     * @param data This operation does not return a value.
     * @param {String} response The complete HTTP response.
     */

    /**
     * Create user
     * @param {Object} opts Optional parameters
     * @param {module:model/NewUserRequest} opts.newUserRequest 
     * @param {module:api/UserApi~createUserCallback} callback The callback function, accepting three arguments: error, data, response
     */
    createUser(opts, callback) {
      opts = opts || {};
      let postBody = opts['newUserRequest'];

      let pathParams = {
      };
      let queryParams = {
      };
      let headerParams = {
      };
      let formParams = {
      };

      let authNames = [];
      let contentTypes = ['application/json'];
      let accepts = ['application/json'];
      let returnType = null;
      return this.apiClient.callApi(
        '/users', 'POST',
        pathParams, queryParams, headerParams, formParams, postBody,
        authNames, contentTypes, accepts, returnType, null, callback
      );
    }

I did some research how the UserApi must send the request and found the line
let postBody = opts['newUserRequest'];

This differs from the generated pet store api from the examples:
https://github.com/OpenAPITools/openapi-generator/blob/master/samples/client/petstore/javascript/src/api/PetApi.js
check the addPet function

How should I use my generated code to get it working?

Compare the generated UserApi.createUser implementation with samples/client/petstore/javascript/src/api/PetApi.js and the usage documented in samples/client/petstore/javascript/docs/PetApi.md#addPet. Start by checking how the generated method expects newUserRequest and how the request callback is invoked; done means reproducing a request to /users and confirming the callback receives the result or error.
