object BSONDocumentFormat in trait BSONFormats is deprecated: 0.11.9

Question

I have a following function that takes in an input JSON and validates it against a given JSON-Schema using the "com.eclipsesource" %% "play-json-schema-validator" % "0.6.2". This whole setup is working great until I have started getting warnings about a deprecated library. As you can see, I am using Ok(Json.toJson(result))) to convert result of type scala.List[BSONDocument] to JSON. This is done using the import play.modules.reactivemongo.json.BSONFormats._ library. I really like the easiness and simplicity of this conversion however, I am getting the following warning:

object BSONDocumentFormat in trait BSONFormats is deprecated: 0.11.9

And, here's my actual function:

def getMessage(campaignID: String, revision: Int, transactionID: Int ) = 
   Action.async { implicit request =>

  db.getDocument(campaignID, revision, transactionID)
  .map(result =>
  Ok(Json.toJson(result)))
  .recover {case ex: IOException => InternalServerError("Please install MongoDB")}

}

Is there an alternate way to do this? Why would the library developer remove such a useful functionality?

As per @cchantep comments, I was able to resolve the issue by replacing:

import play.modules.reactivemongo.json.BSONFormats._

with:

import reactivemongo.play.json.BSONFormats._
