Swagger UI File Upload for Scala Play help

[Lee]

Hello,

I have searched through the group and petstore example but could not find a good Scala example to upload file. 

I managed to get the button to show up on swagger UI with the following annotations:

  @ApiOperation(httpMethod = "POST", consumes = "multipart/form-data")

  @ApiResponses(Array(

    new ApiResponse(code = 400, message = "Invalid file format")))

  @ApiImplicitParams(Array(

    new ApiImplicitParam(value = "Image file to attach", dataType = "file", paramType = "form")))

  def uploadImage = Action.async { request =>

     ...

  }

Unfortunately, when I inspect the data using request.body.asMultipartFormData, all the data lengths were zero.

What am I missing? Please let me know if you need more information to answer my question.

Thanks!
