Hi All.

Maybe you could help me on this one. I get sporadic "Missing Values" - JsonException in the client frontend (only in IE9).

It is hard to identify which Layer could cause the problem. Is the browser breaking the request? the server? Maybe you've already seen this bug before.

For Example:
 
Request:
{"id":3,"method":"ListVehicles","params":["0E68FA58-3385-4028-93ED-6A82A96095FA"]}
 
Response:
{"id":null,"error":{"name":"JsonException","message":"Missing value.","stackTrace":" at Jayrock.Json.JsonTextReader.Parse()\r\n at Jayrock.Json.JsonReaderBase.Read()\r\n at Jayrock.Json.JsonReader.MoveToContent()\r\n at Jayrock.Json.JsonReader.ReadToken(JsonTokenClass token)\r\n at Jayrock.JsonRpc.JsonRpcDispatcher.ParseRequest(JsonReader input)","errors":[{"name":"JsonException","message":"Missing value."}]}}
 


Or
 
Request Body:
{"id":1,"method":"SetInstance","params":["1"]}
Response Body:
{"id":null,"error":{"name":"JsonException","message":"Missing value.","errors":[{"name":"JsonException","message":"Missing value."}]}}


Thank you in advance for any tipps.

Regards.

If it is sporadic, my hunch is that one of the layers is consuming or eating up the stream. When it gets to Jayrock, the stream is at its end and it throws the “Missing value.” error. You can try this to get the same error:

JsonConvert.Import(new StreamReader(Stream.Null));

Hope that sheds some light.

Just FYI,
The client had a Cisco Firewall, which managed to break and cut the request body. (some creepy settings). The whole request body was missing in the inbounding request server side.
Adding the domain to the Whitelist of the Cisco Firewall seems to avoid the missing data behaviour.

So, the problem wasn't related to jayrock at all.

Thank you anyway.

Thanks for taking a moment to drop in with your discoveries. Glad to hear it wasn't Jayrock after all. Now we can all return to the regularly scheduled program. :)
