Hi guys. I'm using play-grpc-runtime and trying to handle errors properly. When I match the exception type and return something like this

case Failure(e: KeycloakRealmException) =>
        Future.failed(Status.NOT_FOUND.withDescription(e.getMessage).asRuntimeException())

I see this message in the log

[error] a.a.ActorSystemImpl - Unhandled error: [NOT_FOUND: Can't find tenant with id ab7ff915-9843-402a-aa87-60f86dc41f45].
io.grpc.StatusRuntimeException: NOT_FOUND: Can't find tenant with id ab7ff915-9843-402a-aa87-60f86dc41f45
    at io.grpc.Status.asRuntimeException(Status.java:524)

And the service returns this

ERROR:
  Code: Internal
  Message:

Any ideas why it could be unhandled? Could it be the limitation of the play-grpc-runtime?

Andrey

@green-creeper

Moreover,
If I make method like this

override def delete(in: DeleteClientRequest): Future[DeleteClientResponse] =
    Future.failed(Status.NOT_FOUND.withDescription("WTF").asRuntimeException())

I see the same

[error] a.a.ActorSystemImpl - Unhandled error: [NOT_FOUND: WTF].
io.grpc.StatusRuntimeException: NOT_FOUND: WTF
    at io.grpc.Status.asRuntimeException(Status.java:524)

And output

ERROR:
  Code: Internal
  Message:

Andrey

@green-creeper

Ok, regarding above problem, there should be special exception type Future.failed(new GrpcServiceException(status))

Sorry if I bother you. I want to use I18n to setup multi language for java project. But I can not find tutorial for it. Could you help me? Thank you very much!

Hello, do you guys know of any "larger" project that uses subprojects I could look at? Preferably in JavaPlay.

Paul Schwarz

@paulschwarz

Morning. I working in a Java environment using Gradle. I want to build a library that I can publish to a Nexus repo and then pull into Play. If it had no dependency on Play, that would be fairly straight forward. However, in this case, the library is aware of Play and therefore needs Play dependencies at least at compile time. What artefact should I include in my Java project to supply the compile-time dependencies for Play?

How do I stop sbt-play from marking my public directory as a resources root in IntelliJ?

@andriisalivonov

I've noticed that there is no example for gRPC in https://github.com/playframework/play-samples/tree/2.6.x although I cannot find which problem might not allow to do it. Since in 2.6.x akka http sever supported everything should work.

Is there any potential problem that can stop me from implementing gRPC on play 2.6.x?

Will Sargent

@wsargent

Play 2.6 doesn’t mean Akka 2.6

sjaanus

@sjaanus

hi, any tips what to do with requests getting net::ERR_CONNECTION_RESET after couple of minutes? I have play 2.6 and application.conf has set:
play.server.http.idleTimeout=3600
play.server.akka.requestTimeout=3600

Hi there. Anyone here confident enough with Play WebSockets to answer a simple (?) question? :D

Antoine Doeraene

@sherpal

shoot the question, I (we)'ll do our best <3

Christian Hessenbruch

@bastaware

I've created a backend that runs on port 9000. It serves HTTP and websocket. I've installed lighttpd in front to handle SSL. Everything works as expected when I access the backend directly on port 9000, but when accessing via wss it stops working.

After a lot of investigating I discovered that lighttpd appends 'close' when forwarding the websocket request to that backend. I got assistance from the author of lighttpd, and he tells me to make sure that the backend doesn't close the connection.

Please see this thread for more details:
https://discuss.lightbend.com/t/secure-websocket-with-proxy-connection-closed/8490

Antoine Doeraene

@sherpal

have you tried a web socket route as dumb as this: https://www.playframework.com/documentation/2.8.x/ScalaWebSockets#Handling-WebSockets-with-Akka-streams-directly ?

also, when you say it closes, do you mean directly? Because Play does not keep alive connections more than 1 minute if there is no message passing by (you need to manually send "heart beat" messages if the connection can idle for so long)

Christian Hessenbruch

@bastaware

No I've only tried the actor model. It seems simple and fit the application great.

Yes it closes instantly. Here is a screenshot (the last image) that shows a connection made from Postman.

https://imgur.com/a/dK3ADdt

This is how the request looks when Postman connects directly to port 9000:

GET /ws HTTP/1.1
Sec-WebSocket-Version: 13
Sec-WebSocket-Key: kiliUHe9b7TjqgBp5sNVJQ==
Connection: Upgrade
Upgrade: websocket
Sec-WebSocket-Extensions: permessage-deflate; client_max_window_bits
Host: xxxxxx.com:9000

This is what hits the backend server when doing a wss request from Postman to lighttpd

GET /ws HTTP/1.1
Host: xxxxxx.com
Sec-WebSocket-Version: 13
Sec-WebSocket-Key: vrPH46cZiHuAHfkVS1BxGw==
Upgrade: websocket
Sec-WebSocket-Extensions: permessage-deflate; client_max_window_bits
X-Forwarded-For: 213.32.242.139
X-Host: xxxxxx.com
X-Forwarded-Host: xxxxxx.com
X-Forwarded-Proto: https
Connection: close, upgrade

Notice how lighttpd preprends close to "Connection" argument

Christian Hessenbruch

@bastaware

I guess this tells Play to close the connection. But according to the author of lighttpd, this is not correct behavior.

Antoine Doeraene

@sherpal

hum, and an even dumber question: does the connection close if you connect to play directly? without going through lighttpd?

Christian Hessenbruch

@bastaware

It just keeps alive :) Life is great when I connect directly.

Hello, is there a known problem with playframework 2.8.x and java16 and the guice module?

nice: just had to add "com.google.inject" % "guice" % "5.0.1", and the tests run again!

Hi everyone, I was wondering if there is a possibility to merge the logic for different actions that are duplicated to capture the possibilities to handle different types of requests, say merging the following to actions their duplicated logic:

object AuthenticatedUserActionHandler {
  private val loginRequired: (String, String) =
    Global.FLASH_WARNING_KEY -> "You are required to be logged in to view this content"

  class AuthenticatedUserAction @Inject()(parser: BodyParsers.Default)(
    implicit ec: ExecutionContext) extends ActionBuilderImpl(parser) {

    override def invokeBlock[A](request: Request[A], block: Request[A] => Future[Result]): Future[Result] = {
      request.session.get(global.Global.SESSION_USERNAME_KEY) match {
        case None => Future.successful(Redirect(routes.HomeController.index).flashing(loginRequired))
        case Some(_) => block(request)
      }
    }

  }

  class AuthenticatedUserActionMessageRequest @Inject()(parser: BodyParsers.Default, messagesApi: MessagesApi)(
    implicit ec: ExecutionContext) extends MessagesActionBuilderImpl(parser, messagesApi) {

    override def invokeBlock[A](request: Request[A], block: MessagesRequest[A] => Future[Result]): Future[Result] = {
      request.session.get(global.Global.SESSION_USERNAME_KEY) match {
        case None => Future.successful(Redirect(routes.HomeController.index).flashing(loginRequired))
        case Some(_) => block(new MessagesRequest[A](request, messagesApi))
      }
    }

  }
}

I’m having some trouble with dependency injection/guice with Scala Playframework.
Given a classes MyController, MyService and MyRequestContext
MyController, MyService are injected classes. MyService is injected into MyController
I have a MyRequestContext object produced during my action composition. I’d like to make this available as an implicit class parameter of MyService in an injected class, per each request.
I’m trying figure out how to do that. I can’t inject it, it doesn’t exist till the request happens. I can make it a method parameter but that gets very verbose. I can break MyService from the DI and instead instanciate it manually per request. This last one works but why have Dependency Injection if I can’t use it in most places?

We are using play2.2.1 and have plans to upgrade the framework to 2.8.x. I know it will be a very big task. Should I do that in steps like from 2.2.1 to 2.x.x -> 2.8.x or try directly migrating to latest version?

Note: Some unresolved dependencies have extra attributes. Check that these dependencies exist with the requested attributes.

Hi did someone hit this playframework/playframework#10936 , any idea how to investigate such case ?

Armin Primadi

@aprimadi

Hello, I'm having problem with play framework default logger. Somehow it's not logging anything to STDOUT even when I set the root level to INFO

// web/conf/logback.xml
<configuration>
  ...

  <logger name="play" level="INFO" />
  <logger name="application" level="DEBUG" />

  <root level="INFO">
    <appender-ref ref="ASYNCFILE" />
    <appender-ref ref="ASYNCSTDOUT" />
    <appender-ref ref="Sentry" />
  </root>

</configuration>

My logback configuration. As far as I know I didn't change anything beside adding Sentry

Armin Primadi

@aprimadi

Actually, never mind, I chose to ditch default Play logger and use scribe instead
