How to make Akka.NET's ClusterClient work?

Question

I'm trying out ClusterClient as per the docs.

However my client test app keeps getting the following error:

Error while creating actor instance of type Akka.Cluster.Tools.Client.ClusterClient with 1 args: (Akka.Cluster.Tools.Client.ClusterClientSettings)
Cause: [akka://TestSystem/user/$a#705838478]: Akka.Actor.ActorInitializationException: Exception during creation ---> System.TypeLoadException: Error while creating actor instance of type Akka.Cluster.Tools.Client.ClusterClient with 1 args: (Akka.Cluster.Tools.Client.ClusterClientSettings) ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentException: failure-detector.heartbeat-interval must be > 0s

   at Akka.Actor.ActorCell.Create(Exception failure)
   at Akka.Actor.ActorCell.SysMsgInvokeAll(EarliestFirstSystemMessageList messages, Int32 currentState)

The minimal code I'm using to get this error:

using (var system = ActorSystem.Create("TestSystem")) {
    system.Settings.InjectTopLevelFallback(ClusterClientReceptionist.DefaultConfig());
    var settings = ClusterClientSettings.Create(system);
    var client = system.ActorOf(ClusterClient.Props(settings));
    Console.Write("Press any key to exit...");
    Console.ReadKey();
}

The HOCON config for the client contains:

akka {
  actor {
    provider = "Akka.Remote.RemoteActorRefProvider, Akka.Remote"
  }

  remote {
    helios.tcp {
      port = 0
      hostname = localhost
    }
  }

  cluster {
    client {
      initial-contacts: ["akka.tcp://TestSystem@localhost:8082/user/receptionist"]
    }
  }
}

Also checked the settings variable, seemed to be populated and looks ok to me:

Tried several random stuff to actually fulfill the error message:

failure-detector.heartbeat-interval must be > 0s

including various permutation of HOCON entries, but to no avail.

Anything else I missed out?

Update #1

Modified HOCON to initialize Akka.Remote. Still received what looks like the same error message.

But now it is stating:

failure-detector.heartbeat-interval must be > 0s

Previously it was stating:

failure-detector.acceptable-heartbeat-pause must be >= 0s

Answer 1

Managed to make it working now.

The cause of the issue: I was using Akka.Cluster.Tools latest release version 1.0.6

The fix: Upgraded to the latest beta version 1.1.2.30-beta

p/s: I wished the docs could have specified the minimum NuGet version required to make it work.
