This is what is returned by the Discourse topic lists. I don’t think the lack of a proper title is what is causing the problem. To get actual post content from a topic list, you need to make two API requests. First make an API request to get the topic list. Then from the topics that are returned, you need to get the topic ids and make a request to /t/<topic_id>.json for each topic. Substitute the id of the topic you want for <topic_id>. This second request will return the first 20 posts in the topic.
