Issue with finding akka-pubsub serializer

[joshgarnett]

Akka 1.3 + OSX

After testing a new build of Akka 1.3, my application ran into the following error:

[ERROR][8/25/2017 10:05:55 PM][Thread 0012][[akka://Cluster/system/endpointManager/reliableEndpointWriter-akka.tcp%3A%2F%2FCluster%40127.0.0.1%3A8091-1/endpointWriter#1752422679]] AssociationError [akka.tcp://Cluster@127.0.0.1:9189] -> akka.tcp://Cluster@127.0.0.1:8091: Error [Cannot find serializer with id [9].

If I manually add the serializer to my app.config with the following the error goes away:

akka.actor {
  serializers {
    akka-pubsub = "Akka.Cluster.Tools.PublishSubscribe.Serialization.DistributedPubSubMessageSerializer, Akka.Cluster.Tools"
  }
  serialization-bindings {
    "Akka.Cluster.Tools.PublishSubscribe.IDistributedPubSubMessage, Akka.Cluster.Tools" = akka-pubsub
    "Akka.Cluster.Tools.PublishSubscribe.Internal.SendToOneSubscriber, Akka.Cluster.Tools" = akka-pubsub
  }
  serialization-identifiers {
    "Akka.Cluster.Tools.PublishSubscribe.Serialization.DistributedPubSubMessageSerializer, Akka.Cluster.Tools" = 9
  }
}

It's possible there is an ordering issue when loading the configs that cause the serializer to not be loaded properly.

[Horusiath]

Have you tried to supply DistributedPubSub.DefaultConfig() as fallback for your actor system configuration?

[joshgarnett]

Hey @Horusiath I have not, though my assumption would be this shouldn't be required as Akka should be properly combining the core akka configs in a sane way.

[vasily-kirichenko]

I have the same error and https://github.com/akkadotnet/akka.net/issues/3031#issue-253038174 has not helped. Is there a WOKRING example cluster project to copy the config from?

I have this config on both nodes:

serializers {
              hyperion = "Akka.Serialization.HyperionSerializer, Akka.Serialization.Hyperion"
            }
            serialization-bindings {
              "System.Object" = hyperion
            }

[vasily-kirichenko]

It was Akkling System.create, which adds FsPickler serializer for expressions, after switching to ActorSystem.Create the error gone.

I have the same problem that josh mentioned. When I add the pubsub serializers he pasted in app.config, it goes away. However, we plan to use hyperion serializer. Is there a way to get the ClusterClient working with hyperion serializer? Do I have to do a fallback with DistributedPubSub.DefaultConfig() as Horusiath suggested?

[vasily-kirichenko]

@leo12chandu I use the above config (using Hyperion for everything) and pub sub does work (without WithFallback you mentioned).

[leo12chandu]

@vasily-kirichenko - That did the trick. Thank You!
