Spock Mock не работает, тест выдает исключение NullPointerException ⇐ JAVA

[Anonymous]

У меня проблема с макетированием в spock, моя переменная systemTaskOptional имеет значение null, тест выдает ошибку. Вот мой тестовый код и часть кода с бизнес-логикой, где выбрасывается значение null.
def "should get system tasks and check if done - mark as success" () {
given:
systemTasksRepository.findByUserIdAndDoneFalse(_) >> getSystemTasksAll()
userApiService.getById(_) >> UserSnapshot.builder().storeAuthorities(Set.of(StoreAuthoritySnapshot.builder().role(StoreRole.OWNER).build())).companyAuthority(CompanyAuthoritySnapshot.builder().companyId(1L).build()).build()
systemTasksRepository.findByUserId(_) >> getSystemTasksAll()
systemTasksRepository.findByUserIdAndByTaskCode(_,_) >> Optional.of(SystemTask.builder().build())
when:
List snapshots = tasksService.getSystemTasksAndCheck(1L)
then:
snapshots.size() == 2
1 * systemTasksRepository.findByUserIdAndByTaskCode(1L, RepositoryTasksService.SystemTaskTypes.CREATE_STORE)
1 * systemTasksRepository.findByUserIdAndByTaskCode(1L, RepositoryTasksService.SystemTaskTypes.CREATE_COMPANY)
}

if (notDoneSystemTasks.contains(SystemTaskTypes.CREATE_COMPANY)) {
CompanyAuthoritySnapshot authoritySnapshot = userApiService.getById(userId).getCompanyAuthority();
if (Objects.nonNull(authoritySnapshot) && Objects.nonNull(authoritySnapshot.getCompanyId())) {
Optional systemTaskOptional = systemTasksRepository.findByUserIdAndByTaskCode(userId, SystemTaskTypes.CREATE_COMPANY); systemTask.setDone(true));
}
}

Я определяю сервис следующим образом:
private TasksMapper tasksMapper = Spy()
private SystemTasksRepository systemTasksRepository = Mock()
private UserApiService userApiService = Mock()

@Subject
private TasksService tasksService = new RepositoryTasksService(tasksMapper, systemTasksRepository, userApiService)
