         context.Response.Headers.Add("Access-Control-Allow-Origin", "*"); //Allow Origin

         context.Response.StatusCode = (int)HttpStatusCode.InternalServerError;

         context.Response.ContentType = "application/json";

         var ex = context.Features.Get<IExceptionHandlerFeature>();

         if (ex != null)

         {

             var err = JsonConvert.SerializeObject(ex.Error);

             await context.Response.WriteAsync(err).ConfigureAwait(false);
