S3 java v1 => v2: putObject работает только при отладке - SdkClientException: невозможно выполнить HTTP-запрос: тайм-аут чтения

Question

Я хочу перейти с S3 java v1 на v2, и теперь по какой-то причине небольшой интеграционный тест начал проваливаться.При отладке и пошаговом прохождении он работает.Вот код (у меня работает локальный стек https://github.com/localstack/localstack экземпляр):

@RunWith(SpringRunner::class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class S3ConfigurationTest {

@Autowired
@Qualifier("historicalDataS3")
lateinit var s3: S3Client

@Test
fun `can write and read object on s3`() {
    var bucket = s3.listBuckets().buckets().first()

    val uid = UUID.randomUUID().toString()

    s3.putObject(
        PutObjectRequest.builder().bucket(bucket.name()).key(uid)
            .build(),
        RequestBody.fromString("test test test"))

    val read =
        String(s3.getObject(GetObjectRequest.builder().bucket(bucket.name()).key(uid).build()).readBytes())

    Assertions.assertThat(read).isEqualTo("test test test")
}

, и это исключение коренится в строке putObject:

Что здесь происходит?Что касается примеров, это должно работать https://github.com/awsdocs/aws-doc-sdk-examples/blob/master/javav2/example_code/s3/src/main/java/com/example/s3/S3ObjectOperations.java
