Problem you have encountered: Deploying an OpenAPI swagger file with type=file in a URI's parameter object yields error.


What you expected to happen: Add support to type=file in a parameter object.


Steps to reproduce:

1. Create a OpenAPI swagger file with type=file in a URI's parameter object [1].
2. Deploy it with "gcloud endpoints services deploy SWGGER_FILE.
3. Get the following error message:

location: "unknown location"
kind: ERROR
message: "http: repeated message field 'google.protobuf.Struct.fields' referred to by message 'UploadRequest' cannot be mapped as an HTTP parameter."

Other information (workarounds you have tried, documentation consulted, etc):

[1] OpenAPI 2.0 specification https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#data-types

[2] I don't see I cannot use "file" in https://cloud.google.com/endpoints/docs/openapi/openapi-limitations .

  "/upload":
    post:
      description: "Upload"
      operationId: "upload"
      consumes:
      - "multipart/form-data"
      produces:
      - "application/text"
      responses:
        200:
          description: "Upload OK"
          schema:
            $ref: "#/definitions/echoMessage"
      parameters:
      - description: "Upload a file"
        in: formData
        name: message
