> Failures during queries using QueryableStateClient throw exceptions like UnknownKeyOrNamespace but these are thrown on the server side with its stacktrace included, then serialised and sent over to the client where they are deserialised and re-thrown.
> For debugging it would help a lot if these "server-exceptions" would be encapsulated in new client-exception instances so that we also get the client's stack trace. Especially since failing requests may be caused by the client itself, e.g. non-existing jobs/keys, wrong namespace/serialisers, etc.
