Spreadsheet Server-side error [Unsupported Media Type]

I created a server by referring to the documentation.(Link)
Tried download test. but failed.
In my opinion, the response header is wrong.
Content-Disposition is not returned on my server.

I have attached an example file.

Please tell me a solution.

my code : 
        //To save as excel file
        [AcceptVerbs("Post")]
        [HttpPost]
        [EnableCors("AllowAllOrigins")]
        [Route("Save")]
        [RequestSizeLimit(2147483648)] // e.g. 2 GB request limit
        public IActionResult Save(SaveSettings saveSettings)
        {
            Console.WriteLine("Save");
            return Workbook.Save(saveSettings);
        }

my test page : http://vpn.pspace.com:15080/sheet/

result : {"type":"https://tools.ietf.org/html/rfc7231#section-6.5.13","title":"Unsupported Media Type","status":415,"traceId":"|d696af79-4b7f81d4e4059d5a."}
