Swagger Codegen version: 3.0.65 broke my javascript client code

[ralpheichelberger]

my YAML didn't change
but now every returnType is set to null

I looked at what has changed, but I only found that there was a change vom cli version 43 to 44 and there some java framework changed.

The error occurs if you don't use inline responses but create a response under components / responses like this:

openapi: 3.0.1
info:
  title: Simple API
  version: 1.0.0
  description: Eine einfache API mit einem Array von Objekten als Rückgabewert.

paths:
  /items:
    get:
      summary: Hole ein Array von Objekten
      description: Gibt eine Liste von Objekten zurück.
      responses:
        '200':
          $ref: '#/components/responses/ItemListResponse'

components:
  schemas:
    Item:
      type: object
      properties:
        id:
          type: integer
          example: 1
        name:
          type: string
          example: "Testobjekt"
        price:
          type: number
          format: float
          example: 19.99

  responses:
    ItemListResponse:
      description: Erfolgreiche Antwort mit einer Liste von Objekten.
      content:
        application/json:
          schema:
            type: array
            items:
              $ref: '#/components/schemas/Item'

Then the resulting DefaultApi.js looks like this:

/*

import ApiClient from "../ApiClient";

/**

export default class DefaultApi {

    /**

    */
    constructor(apiClient) {
        this.apiClient = apiClient || ApiClient.instance;
    }

    /**

     */

    /**
     * Hole ein Array von Objekten
     * Gibt eine Liste von Objekten zurück.
     * @param {module:api/DefaultApi~itemsGetCallback} callback The callback function, accepting three arguments: error, data, response
     */
    itemsGet(callback) {
      
      let postBody = null;

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

      let authNames = [];
      let contentTypes = [];
      let accepts = [];
      let returnType = null;

      return this.apiClient.callApi(
        '/items', 'GET',
        pathParams, queryParams, headerParams, formParams, postBody,
        authNames, contentTypes, accepts, returnType, callback
      );
    }

}

And this won't give you the result of the server back.
