Play Scala Oauth Provider Error - scala

Question

I am building a Play Scala project and need an authentication for the apps.
I am using this one : https://github.com/nulab/scala-oauth2-provider as the Oauth Provider libs.
I have implement everything based on the docs. But when implement the Auth on the controller below :
object Token extends MainController with OAuth2Provider {
def accessToken = Action.async { implicit request =>
issueAccessToken(new MyDataHandler()
}
And here my router :
GET /test controllers.Token.test
POST /token controllers.Token.accessToken
When I access localhost/token, i got this error :
And here the error from console :

What do you use Play and scala-oauth2-provider version?
The error looks Play version is different.
If you use Play 2.3, you should use 0.14.0 in scala-oauth2-provider.
See readme.
