I have this test code that is ok in class SimpleReactiveMongoRepositoryTests

Example<ReactivePerson> example = Example.of(new ReactivePerson("foo", "bar", -1)); StepVerifier.create(repository.findById("foo")).expectNextCount(0).verifyComplete();

But if I write this

Example<ReactivePerson> example = Example.of(new ReactivePerson("foo", "bar", -1)); StepVerifier.create(repository.findOne(example)).expectNextCount(0).verifyComplete();

An exception is thrown

java.lang.AssertionError: expectation "expectComplete" failed (expected: onComplete(); actual: onError(java.util.NoSuchElementException: Source was empty))

I think the behaviour should be the same because I can't write this code because an Exception is thrown

myRepository.findOne(Example.of(anExample)) .switchIfEmpty(Mono.error(new DocumentNotFoundException()));
