Edited Issue: Null reference exception with basic program [2152]

Just installed via Nuget:

Install-Package TweetinviAPI

var credentials = TwitterCredentials.CreateCredentials("xxx", "yyy", "zzz", "uuu");
TwitterCredentials.ExecuteOperationWithCredentials(credentials, () =>
{
ITweet t = Tweet.PublishTweet("myTweet");
Console.WriteLine(t);
});

t comes back null, nothing was tweeted?? I double checked the credentials

Tried it from source code, got an exception in GetPublishTweetQuery because tweetDTO.MediasToPublish
is null and the code doesnt test for it?

if (tweetDTO.MediasToPublish.Any())
