That’s a Twitter Finatra Jackson deserializer issue. It seems to require non-null values for non-optional fields. I need to investigate what can we do about it.

Ok I will fork the Finatra.

One potential issue there is that they seem to make mandatory only case class fields. But since we use case classes everywhere in the API it’s not a problem for us right now.
