de.flapdoodle.embed.mongo fails on GitLab CI - mongodb

Question

I have a Spring Boot 2 application running some unit testing using Embendded Mongo (de.flapdoodle.embed.mongo).
The tests when I run locally using
/gradlew clean build
It runs normally.
However, when the same application is built on GitLab CI/CD I find the following error:
WafiraApplicationTests > contextLoads() FAILED
java.lang.IllegalStateException at DefaultCacheAwareContextLoaderDelegate.java:132

This is an example of one test case below:
#DataMongoTest
public class DepositRepositoryTest {
#Autowired
private DepositRepository depositRepository;
#Test
void save(){
var deposit = DataGenerator.getDeposityEntityWithFixedValues();
depositRepository.save(deposit);
AtomicInteger atomicInteger = new AtomicInteger(0);
depositRepository.findAll().forEach(it -> atomicInteger.addAndGet(1));
assertThat(atomicInteger.get()).isEqualTo(1);
}
Any ideas?
