Parameter type array in form data not support?

[TranAn90]

I want to add a parameter type array in form data to upload multiple files but it seem not work.

My Swagger json

parameters:
        ...
        - name: files
          in: formData
          description: ''
          required: true
          schema:
            type: array
            items:
              type: object
              properties:
                file:
                  type: file
                caption:
                  type: string
 responses:
        '200':...

and I got this error:

Swagger Error
Not a valid parameter definition

That's because it's not supported in the spec - see OAI/OpenAPI-Specification#254. Unfortunately, this can't be done right now.
