Spray-json None values are always converted to null. How to change this?

See original GitHub issue

Spray converts None values to null only when NullOptions trait is added but by default it doesn’t add those fields to JSON. When using kebs implicitly[RootJsonFormat[xxx]], it converts None values to null. Example of such case: https://scastie.scala-lang.org/myDisconnect/tgnMaqh4QcCdQWDBWQZT5A/7 see f4 field (this is also visible in Kebs tests) Is it possible to change this behaviour in Kebs and ignore None values?

Note: This seems to be happening when a case class has more than 22 parameters
