Play ScalaWebSocket v2.5.* Upgrade to WebSocket required - scala

Question

I'm trying to create a websocket using Play ScalaWebsockets. I referred to their documentation which is located here. And as of the moment, I am using these SBT plugins which is required to use Play's websockets.
"com.typesafe.akka" %% "akka-actor" % "2.4.7",
"com.typesafe.akka" %% "akka-testkit" % "2.4.7" % "test",
This is my Actor:
package actors.chat
import akka.actor._
import akka.stream._
object ChatSocketActor {
def props(out: ActorRef) = Props(new ChatSocketActor(out))
}
class ChatSocketActor(out: ActorRef) extends Actor {
def receive = {
case msg: String =>
out ! ("I received your message: " + msg)
}
}
In my Controller, I have this socket function:
#Singleton
class ChatController #Inject()(
val messagesApi: MessagesApi,
val pageMetaApi: PageMetaApi,
implicit val materializer: Materializer,
implicit val system: ActorSystem,
implicit val wja: WebJarAssets
) extends Controller with I18nSupport with PageMetaSupport {
import actors.chat.ChatSocketActor
def index = Action { implicit request =>
Ok(views.html.chat.index());
}
def socket = WebSocket.accept[String, String] { request =>
ActorFlow.actorRef(out => ChatSocketActor.props(out))
}
}
After I compile and refresh the browser, I get this 426 response.
Upgrade to WebSocket required
Is there something I missed?
PROBLEM SOLVED:
I'm new to websockets. Problem was I was accessing the socket on a standard HTTP. I changed my routes to
# Chat
GET /chat controllers.ChatController.index
GET /websocket controllers.ChatController.socket
And a JS script in the /chat page which calls the websocket connection.
var ws = new WebSocket("ws://127.0.0.1:9000/websocket");
console.log(ws)
