如何在OpenAPI 2.0中为相同的操作定义路径和formData参数?

/test/{id}/relationships/image 。我想使用OpenAPI 2.0(Swagger 2.0)描述这个端点。

swagger: '2.0'
info:
  title: API
  version: 1.0.0
host: api.server.de
schemes:
  - https
produces:
  - application/json
paths:
  '/test/{id}/relationships/image':
    post:
      operationId: addImage
      consumes:
        - multipart/form-data
      parameters:
        - in: path
          name: id
          required: true
          schema:
            type: integer
            format: int32
        - in: formData
          name: file
          type: file
          required: true
          description: The file to upload.
        - in: formData
          name: metadata
          type: string
          required: false
          description: Description of file contents.
      responses:
        '202':
          description: Uploaded

但Swagger Editor显示了错误:

路径['/test/{id}/relationships/image']。post.parameters[0]。在should中 formData,查询跳转到第17行

架构错误 路径['/test/{id}/relationships/image']。参数[0]不应 具有其他属性additionalProperty:schema、in、name、, 需要跳到17号线

我做错了什么?
