When executing:

```
s3AsyncClient.headBucket(HeadBucketRequest.builder()
                    .bucket("local-stack-test-bucket")
                    .build()).join();
```

We get this exception thrown (Java): java.util.concurrent.CompletionException: software.amazon.awssdk.services.s3.model.S3Exception: null (Service: S3, Status Code: 502, Request ID: null)

I narrowed this down to db4cddea4e4844c1241cca5ac22ecbde08e52064 and found the problem. PR incoming shortly.
