JsonReaderException when trying to read string from PlugExtraData

[kriz83]

With the code from this thread, I get a JsonReaderException when trying to retrieve a Named PlugExtra Property:

HsDevice hsDevice = null;
foreach (var devRef in HomeSeerSystem.GetRefsByInterface(Id, true))
{
    var device = HomeSeerSystem.GetDeviceWithFeaturesByRef(devRef);
    try
    {
[COLOR=#FF0000][B]// CRASHES HERE[/B][/COLOR]
        if (e.NodeId == device.PlugExtraData.GetNamed<string>("id"))
        {
            hsDevice = device;
            break;
        }
    }
    catch (KeyNotFoundException)
    {
        //TODO: proper exception logging
    }
}

Help would be very welcome over here. Trying to add features AFTER the device has been created (features become known quite a few seconds after the device is created).

Workaround:

device.PlugExtraData["id"]
