Hello, Emmanuel , Please check you ajax call for request for the API. Remove Type as json. Also In parameter it requires file parameter of type HttpPostedFileBase so it should be like below public ActionResult FileUpload(HttpPostedFileBase file){} Thanks Vishal Joshi

There are a few issues with your code. Here’s a corrected version: public ActionResult FileUpload(HttpPostedFileBase file) { string relativePath = string.Empty; if (file != null && file.ContentLength > 0) { var fileName = Path.GetFileName(file.FileName); var path = Path.Combine(Server.MapPath("~/uploads/"), fileName); file.SaveAs(path); relativePath = Url.Content("~/uploads/" + fileName); } return Json(new { path = relativePath }, JsonRequestBehavior.AllowGet); } In this corrected version: The parameter file is of type HttpPostedFileBase which represents an uploaded file. We check if the file is not null and if it has content. We get the file name and combine it with the path where we want to save the file. In this case, it’s the “uploads” folder at the root of the server. We save the file using file.SaveAs(path) . We create the relative path for the uploaded file. Finally, we return the relative path as JSON. Please make sure to replace "~/uploads/" with the actual path where you want to save the files on your server. Also, ensure that the server has the necessary write permissions to that directory. Remember, this is a basic example and doesn’t include error handling and file validation (like checking file size, file type etc.) which you should implement in a production environment. Thanks
