TestContainers and LocalStack S3: Invalid S3 URI: hostname does not appear to be a valid S3 endpoint

I am trying to extract AWS Object URL via the following code:

s3AsyncClient.utilities()
                .getUrl(r -> r.region(awsRegion).bucket(bucketName).key(key));

For Integration tests where I am using TestContainers and LocalStack S3, the returned URL looks like this:

        http://127.0.0.1:51435/my-bucket/games/123.json

The URL looks good to me, but when I try to transform URL to S3Uri:

        S3Uri s3Uri = s3AsyncClient.utilities().parseUri(url.toURI());

I am getting the following error:

java.lang.IllegalArgumentException: Invalid S3 URI: hostname does not appear to be a valid S3 endpoint: http://127.0.0.1:51435/my-bucket/games/123.json

Seems that the aws parser doesn’t accept 127.0.0.1 as a valid s3 endpoint, but what should I do?
Not sure that I can force the AWS parser to accept 127.0.0.1 as a valid host, but maybe it is possible somehow to configure LocalStack S3 to return an acceptable hostname instead of an IP address?

Current Localstack S3 configuration see below:

    private static final LocalStackContainer LOCAL_STACK_CONTAINER = new LocalStackContainer(LOCAL_STACK_IMAGE)
            .withServices(LocalStackContainer.Service.S3);

    static {
        LOCAL_STACK_CONTAINER.start();
    }

    @DynamicPropertySource
    static void s3Properties(final DynamicPropertyRegistry registry) {
        registry.add("ssp.s3.region", LOCAL_STACK_CONTAINER::getRegion);
        registry.add("ssp.s3.endpoint", () -> LOCAL_STACK_CONTAINER.getEndpointOverride(LocalStackContainer.Service.S3));
    }
