引用多个预定义的swagger 2.0参数定义抛出错误

Question

我在swagger 2.0文件中定义了两个可重用参数：

parameters:
  cursorParam:
    name: cursor
    in: query
    description: Pagination cursor.
    required: false
    type: string       
  limitParam:
    name: limit
    in: query
    description: Result limiter.
    required: false
    type: integer 

然后在我的路由定义中（在本例中为GET），我尝试这样引用这两个：

parameters:
    - $ref: '#/parameters/cursorParam'
    - $ref: '#/parameters/limitParam'  

如果我使用一个$ref，它似乎工作正常(没有编译错误)，但是如果我尝试两个都使用，它会看着我:

Operation parameter already defined: undefined
at paths ▹ /users ▹ get ▹ parameters ▹ 1 ▹ name

Operation parameter already defined: undefined
at paths ▹ /authorisations ▹ get ▹ parameters ▹ 1 ▹ name

此外，如果我在查询字符串中传递这些参数并输出＜code＞req.swagger。params＜/code＞，我得到一个空对象。我做错了什么？

这是规范的完整SSCCE，生成相同的错误：

您似乎使用的是旧版本的 a127。最近修复了 Swagger 文档所有部分缺乏参考支持的问题，因此更新应该可以解决此问题。
