How to properly use PlayJsonCodecs.JsValueCodec? #15
Description
I tried a super simple App using play.api.libs.json.Json:
import org.velvia.msgpack
import org.velvia.msgpack.PlayJsonCodecs.JsValueCodec
import play.api.libs.json.{JsValue, Json}
object Velvia extends App {
val js: JsValue = Json.parse("""{"amount":40,"currency":"USD","label":"$40.00"}""")
val p: Array[Byte] = msgpack.pack(js)
println(java.util.Arrays.toString(p))
val u = msgpack.unpack[JsValue](p)
}is returning:
[-125, -90, 97, 109, 111, 117, 110, 116, -110, 0, -60, 1, 40, -88, 99, 117, 114, 114, 101, 110, 99, 121, -93, 85, 83, 68, -91, 108, 97, 98, 101, 108, -90, 36, 52, 48, 46, 48, 48]

I am using
libraryDependencies += "com.typesafe.play" %% "play-json" % "2.6.6"
libraryDependencies += "org.velvia" %% "msgpack4s" % "0.6.0"What am I doing wrong?
