SpringBoot java.lang.IllegalStateException: No transactional EntityManager found

I am using Spring Boot version 2.3.12.RELEASE.

Tests that use TestEntityManager are failing with the following error:

java.lang.IllegalStateException: No transactional EntityManager found

Sample test:

@DataJpaTest
@Transactional
@AutoConfigureTestEntityManager
public class SubscriptionRepositoryTest {
    @Autowired
    private SubscriptionRepository subscriptionRepository;

    @Autowired
    private TestEntityManager entityManager;

    @Nested
    class FindUserActiveSubscription {

        @Test
        public void shouldReturnSubscription_whenUserHasActiveSubscription() {
            Subscription subscription = new Subscription();
            subscription.setId("1");
            subscription.setUserId("testuserid");
            subscription.setEndDate(LocalDateTime.now().plusDays(1));
            subscription.setStatus(SubscriptionStatus.ACTIVE);
            entityManager.persist(subscription);

            subscription = subscriptionRepository.findUserActiveSubscription("testuserid");

            Assertions.assertNotNull(subscription);
        }
    }
}

@ShaimaaSabry thanks for the report but a partial code snippet is not enough for us to figure out what is going on. Can you please move that code in text in an actual project we can run to reproduce the problem? We can share it with us as a zip attached to this issue or using a link to a GitHub repository.

Since I don't know if this counts as a bug, I will just post it here in case someone stumbles upon this. @Transactional annotation only applies for the annotated class, not it's inner classes. But annotating the inner class is not enough to make it work. I don't have a better solution than just removing the inner class.
