Having trouble running Akka proof-of-concept for Akka Event Sourcing

Hi,

I am just trying to run a small in-memory proof of concept using Akka Event Sourcing.

Entry point here: akka_test/main.kt at master · NatElkins/akka_test · GitHub

Configuration here: akka_test/application.conf at master · NatElkins/akka_test · GitHub

It’s mostly cobbled together from various tutorials and copy-pasting from things I read online.

When I run it, here is the error I receive:

Exception occurred
java.util.concurrent.ExecutionException: akka.pattern.AskTimeoutException: Ask timed out on [EntityRef(EntityTypeKey[Command](Counter), A)] after [5000 ms]. Message of type [Command$Get]. A typical reason for `AskTimeoutException` is that the recipient actor didn't send a reply.

This is probably because the cluster never got set up properly. That said, there is no other error indicating anything went wrong. So I’m not really sure how to proceed from here.

Can anybody point me in the right direction on how to get this working?

Thank you!
