CreatePost() Exception

[PureKafka]

When attempting to add a post with HelpCenter.Posts.CreatePost() the following exception is thrown: "JSON integer 1234567897 is too large or small for an Int32. Path 'post.author_id', line 1, position 3823." It appears the post model object's AuthorID property is of type int but it is trying to use the Zendesk user ID which is long.
