Hey guys. I’m trying to get latest posts with help of Discourse Api gem.  
I’ve added next lines to my initializer:

```plaintext
module DiscourseApi
  module API
    module Posts
      def latest_posts(params = {})
        response = get('/posts', params)
        response[:body]['latest_posts']
      end
    end
  end
end

```

On Friday everything worked fine, I was able to get latest posts. But now it responses with 500 status

Fixed the issue by deleting the post with the absent topic.
