Uploading file using Ajax & Dramatic IIS

Question

Hi Guys

 

Im doing a file upload, at first i was using fineuploader, then changed to simple ajax. The error i get is similar the "xhr:An unhandled exception was thrown by the Web Application." Now this works locally but doesn't work on the server, what am I missing on IIS configs? Kindly assist.

 

//Below is the JS 

var formData = new FormData();
        var file = $('#fileID')[0];

        formData.append('file', file.files[0]);
        $.ajax({
            url: '/api/document/uploads/',
            type: 'POST',
            data: formData,
            contentType: false,
            processData: false,
            success: function (result) {

            },
            error: function (result) {

            }
        });

//Below is the api

[HttpPost]
[Route("api/document/uploads")]
public async Task<object> UploadDoc()
{
}
