Fineuploader dotnet core

Question

I'm trying to get write Controller (in asp.net core) code to handle my fineuploader requests but it keeps failing to see the request data despite whatever combination of [FromForm] / [FromBody] / "Content-Type": 'application/json' I use. Here is my uploader config in the view page:

var uploader = new qq.FineUploader({
        element: document.getElementById("uploader"),
        request: {
            endpoint: '@Url.Action("AddAttachment", "Util")',
            customHeaders: {
                "RequestVerificationToken": '@GetAntiXsrfRequestToken()',
                "Content-Type": 'application/json'
            }
        },

And here is my controller code - not alot for now, I just literally want to see some data getting sent.

public JsonResult AddAttachment([FromForm] Object o){
         //var x = HttpContext.Request;
         //return Json(x);
         if(o == null){
             return Json("no data");
         }else{
             return Json(o);
         }
    }

and her is what I see fineuploader sending to the server via the network tab in the chrome devtools:

Content-Disposition: form-data; name="test"

Can anyone see the mistake I'm making?

If everything's wired up correctly, you should be able to see your file via Request.Form.Files in the controller.

I was trying to get it as a byte array by action's parameters but had no luck. Try this instead.
