I am using following code to add new track to an ready running Filtered Stream, using Tweetinvi C# library.
------ Code ref: http://tweetinvi.codeplex.com/discussions/541286 -------
filteredStream.StartStreamMatchingAnyCondition(); // OR // filteredStream.ResumeStream();
As soon as the last line executes, it just STOPS tracking any tweets from any of already tracked users (@mentions). And after some time, the stream automatically ended up with following error:
“Value can not be Null. Parameter name: source”
Any help please?
