I have a very simple application that is trying to get a user and then retrieve the user timeline for that user
TwitterCredentials.SetCredentials("cred1","cred2", "cred3","cred4");
var user = Tweetinvi.User.GetUserFromScreenName("ladygaga");
var timelineTweets = user.GetUserTimeline();
This works fine on my local machine. However, when I deploy this to the server the user is null and I get a Object reference not set to an instance of an object. Looking at the network traffic there is no call going out to the twitter api.
Any ideas what could be causing this issue?
