How to check if returned actor proxy instance is valid

Question

Let's assume the following code snippet as the example:

        ICustomActor puller = ActorProxy.Create<ICustomActor>(ActorId.CreateRandom(),
            new Uri("some_actor_URI"));

The ActorProxy.Create works in a way that even if some_actor_URI is incorrect, there is no exception thrown or null returned. The result is always some proxy object. When invoking an actor's method on that proxy the replica crashes without exception.

The problem is that there is no obvious way to check if the resolved proxy is correct.

How can I check if the resolved actor proxy instance leads to the existing Service Fabric actor instance?
