JSonconverter can't deserialize Akka.Actor.Status.Failure

[AndreSteenbergen]

Akka 1.3.8
.Net Core 2.0

Create an object of type Akka.Actor.Status.Failure and serialize using JsonConverter. It will trhrow an exception about JObject not being to cast to JValue

This is probably caused by the Exception.

@AndreSteenbergen any idea what the underlying exception was?

[AndreSteenbergen]

In my case it was Task.Cancelled Exception, inside AggregateException

[Aaronontheweb]

Ok, that shouldn't be the end of the world. This should be easy enough to reproduce. Happened over an Akka.Remote connection between two .NET Core 2.0 nodes?

[AndreSteenbergen]

Yes, in a webcrawler project modified from the examples

[AndreSteenbergen]

Bug report is faulted, the deserialization gives errors, I don't know which part is at fault.

Akka 1.3.14

I have currently a related problem with RemoteDeploy

An agent is remote deployed and make some work with Akka.Streams.
It throws an System.InvalidOperationException inside SelectAsync(1, ...) of the stream
The exception is handled with the default supervisor strategy and send back to the Deployer.

The deployer throws on receive.

I made a separate topic #3903 on the problem

its not realy a problem with the json serializer.
If NodeA RemoteDeployes to NodeB work.
NobeB can use unknown assemblies to NodeA
like SQL-Client, EventStore-Client ...

[Aaronontheweb]

Real issue here is #3903 - serialization of exceptions in Akka.Remote payloads. Going to address the issue there.
