Twitterizer TwittterTimeline NewtonSoft.JSON.JsonSerializationException problems

Question

The following code raises NewtonSoft.JSON.JsonSerializationException {"Unexpected token while deserializing an object: StartObject. Line 1, position 1884." }

Twitterizer version: 2.4.0.26532 NewtonSoft.Json = 4.0.7.0 (set by adding Nu-GET to the visual studio)

Is there something I am missing or not getting?

class Program { static void Main(string[] _args) { Logger.Write("Calling Twitter", Constants.TWITTER_AGREGATOR_LOG_CATEGORY); UserTimelineOptions options = new UserTimelineOptions(); options.ScreenName = "as_tuce2"; TwitterResponse<TwitterStatusCollection> tweets = TwitterTimeline.UserTimeline(options); //throws exception OAuthTokens tokens = new OAuthTokens(); tokens.AccessToken = // removed... tokens.AccessTokenSecret = // removed... tokens.ConsumerKey = // removed... tokens.ConsumerSecret = // removed... UserTimelineOptions userOptions = new UserTimelineOptions(); userOptions.IncludeRetweets = false; userOptions.ScreenName = "as_tuce2"; userOptions.UseSSL = true; userOptions.Count = 20; TwitterResponse<TwitterUser> showUserResponse = TwitterUser.Show(tokens, "as_tuce2"); //ok TwitterResponse<TwitterStatusCollection> timelineResponse = TwitterTimeline.UserTimeline(tokens); //throws exception Console.ReadLine(); } }

Thanks for posting this. I need to look at it and find out what the new version of json.net has changed.

For posterity, here is a forum topic where you also reported an error.
