昂首阔步yaml / yml oneOf不起作用

Question

我目前正在构建我们的REST API，实现我的文件类型时遇到困难。文件可以来自用户，也可以来自组。我使用oneOf尝试了此操作，但出现错误。这是我的代码和错误：

File:
  type: object
  properties:
    owner:
      oneOf:
        - $ref: "#/definitions/User"
        - $ref: "#/definitions/Group"
      description: Owner of the File

错误：

对不起，格式，但这是错误消息... 当我说对了时，它会因为oneOf而失败，但是正如here oneOf所述，它在这里完全可用。

请坐下一个小时，以帮助我解决此问题
