Describe the problem

When my task fails, I leave the exception to propagate out of the task itself. Then, I catch it when I do ray.get and handle the exception. But I still get a bit later a message Possible unhandled error from worker. How exactly one should handle the error to not get this message? I assumed that this message would be shown only if I have not done ray.get in a reasonable time.
