How to setup a Supervisor Strategy for a child?

[lillo42]

Hello folks,

I'm playing with Proto.Actor and I'm trying to use a supervisor for a child actor, but it isn't been invocated, do you know what could be my issue?

A bit of context, I'm creating a Actor A from ActorSystem without supervisor, then the Actor A will spawn an Actor B with a supervisor.

When the Actor B is failing my supervisor isn't been invoked.

My main class

var system = new ActorSystem();
var props = Props.FromProducer(() => new SocketActor());

...
var actor = system.Root.Spawn(props);
system.Root.Send(actor, new SocketAccepted(socket));

Socket Actor

public class SocketActor : IActor
{
    public async Task ReceiveAsync(IContext context)
    {
        if (context.Message is not SocketAccepted socketAccepted)
        {
            return;
        }

         ...
        
        var props = Props
            .FromProducer(() => new ProcessActor())
            .WithChildSupervisorStrategy(new OneForOneStrategy( 
                (_, exception) =>
                {
                    Console.WriteLine("Error: {0}", exception);
                    return SupervisorDirective.Restart;
                },
                3,
                TimeSpan.FromSeconds(1)));
        var actor = context.SpawnNamed(props, "json-serializer");
        context.Send(actor, new SocketReceived(buffer));
    }
}

The ProcessActor

public class ProcessActor : IActor
{
    public Task ReceiveAsync(IContext context)
    {
        if (context.Message is not SocketReceived socketReceived)
        {
            return Task.CompletedTask;
        }

        var json = JsonSerializer.Deserialize<Sample>(socketReceived.Data)!;
        Console.WriteLine("Received sample with id: {0} and name: {1}", json.Id, json.Name);
        return Task.CompletedTask;
    }
}
