Type conversion doesn't handle explicit nulls about json-lenses HOT 3 OPEN

On further investigation it may be beyond the scope of lenses, it seems to be related/identical to spray/spray-json#60.

from json-lenses.

Any updates on this?

Wrapping the optional extract in a Try should fix this:

def extract[T: Reader](p: Lens[Option]): Option[T] =
    Try { p.get[T](value) }.getOrElse(None)

although it's a bit of an hack.

@jrudolph, what's you opinion on this?

If you parse it as an Option[String] instead it will work. As a general rule of thumb: If the value is nullable, use an Option type.
