TweetIds is always null

I am using a linq-to-twitter query to attempt to get a tweet (status) and reply to that status, but the query always returns ID and TweetIds as null. I attempted to use the statusId, but it went through as a tweet and not a response

 var tweets =
            await
            (from tweet in twitterCtx.Status
             where tweet.Type == StatusType.User &&
                   tweet.UserID == {UserId}
             select tweet)
            .ToListAsync();

Any help would be greatly appreciateed

I guess I had to add the @{ScreenNameResponse} before the response. I got it working. Thanks for the quick response.

From the LINQ to Twitter FAQ:

4. Why are ScreenName and/or UserID properties null in the User entity response from Twitter?

The ScreenName and UserID properties are input only, allowing you to see the parameters you provided in your query.

  • For v2.1.x, use the Identifier property, which has the ScreenName and UserID returned from Twitter.
  • For v3.0.x and later, use the ScreenNameResponse and UserIDResponse properties.

A bit of background: Anything used as an input parameter is also looked at in the query response, so if a user omits the parameter in a query but the twitter response contains a value, it was being filtered out of the results. To fix this, I adopted a convention where any return parameters also match input parameters would have a 'Response' suffix. e.g. ScreenName (input) and ScreenNameResponse (output). To find which values are input, the docs for each API call contain the input/filter parameters.

Here's an example, from LINQ to Twitter Samples code:

    static void PrintTweetsResults(List<Status> tweets)
    {
        if (tweets != null)
            tweets.ForEach(tweet => 
            {
                if (tweet != null && tweet.User != null)
                    Console.WriteLine(
                        "ID: [{0}] Name: {1}\n\tTweet: {2}",
                        tweet.StatusID, tweet.User.ScreenNameResponse, tweet.Text);
            });
    }
