Hello,

I ran into an issue using "spring-boot-starter-data-mongodb-reactive". When calling this server method, see two errors ("Async resource cleanup failed after onComplete", "call already closed") on the server (see attached error log). On the GRpc client I see this error: { "error": "13 INTERNAL: Half-closed without a request" }

GRpc server:

public Mono<RequestRegistrationResult> requestRegistration(Mono<RequestRegistrationData> requestRegistrationDataMono) {
  return requestRegistrationDataMono
    .flatMap(request -> registrationsService.requestRegistration(request.getEmail(), request.getPassword()))
    .map(registration -> RequestRegistrationResult.newBuilder().setRegistrationId(uuidToProtobuf(registration.getId())).build());
  );
}

Business service:

public Mono<Registration> requestRegistration(String email, String password) {
  return registrationsRepository.save(new Registration(UUID.randomUUID(), email, password, UUID.randomUUID()));
}

Repository:

@Repository
public interface RegistrationsRepository extends ReactiveMongoRepository<Registration, UUID> {}

Interestingly enough, if I rewrite the code on the server like this (which is not ideal), everything works fine:

public Mono<RequestRegistrationResult> requestRegistration(Mono<RequestRegistrationData> requestRegistrationDataMono) {
  return Mono.just(
    requestRegistrationDataMono
      .flatMap(request -> registrationsService.requestRegistration(request.getEmail(), request.getPassword()))
      .map(registration -> RequestRegistrationResult.newBuilder().setRegistrationId(uuidToProtobuf(registration.getId())).build())
      .block()
  );
}

Here is the error log:
