I am getting "System.ArgumentException: Invalid JSON primitive:" while i am testing my asp.net web api using fiddler.

 Header is as follows

Content-Type: multipart/form-data; boundary=-------------------------acebdf13572468
User-Agent: Fiddler
Host: trackonpro.in
Content-Length: 8976

Body is as follows

---------------------------acebdf13572468
Content-Disposition: form-data; name="json" 
Content-Type: application/json
{
"WR_id":"0",
"Com_Id": "5",
"Usr_Id":"22",

"App_id":"1",
"Ser_LogNo":"2",

 and the error i am getting is as follows

 

System.ArgumentException: Invalid JSON primitive: "0", "Com_Id": "5", "Usr_Id":"22", "WRC_id":"1", "App_id":"1", "Ser_LogNo":"2", "WR_Comments":"Test", "WR_date":"2015-12-23 01:30:50.000", "WR_Location":"test", "WR_lati":"10.45465", "WR_longi":"70.23654", "Status_id":"11" }. at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer) at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit) at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input) at WebApplication.Areas.Json.Controllers.Work_ReportController.d__4.MoveNext()

Hi,

How is the exception related to Fiddler? Does it disappear if you quit  Fiddler?

The user is attempting to use Fiddler's Composer to perform a POST to a web service.

Is there some reason that you're sending the integer values as quoted strings? Typically, I'd expect these to be sent as unquoted float values.

If fixing that doesn't help, I'd have a look at the formatting of the Date object; dates are particularly tricky to encode in JSON as different platforms have different expectations.
