S3EncryptionClient (not async) Unable to execute HTTP request: headersFuture is still not completed when onStream() is invoked.

The code where I create S3EncryptionClient and call it (3.1.1 library version)

```
private S3EncryptionClient getEncryptionClient(String regionName, KeyPair keyPair) {
return S3EncryptionClient.builder()
.rsaKeyPair(keyPair)
.enableDelayedAuthenticationMode(true)
.enableLegacyUnauthenticatedModes(true)
.enableLegacyWrappingAlgorithms(true)
.wrappedClient(getClient(regionName))
.wrappedAsyncClient(getAsyncClient(regionName))
.build();
}
...
private S3AsyncClient getAsyncClient(String regionName) {
return S3AsyncClient.builder()
.overrideConfiguration(createClientConfiguration())
.region(Region.of(regionName))
.build();
}
..
private ClientOverrideConfiguration createClientConfiguration() {
return S3Client.builder()
.httpClient(
ApacheHttpClient.builder()
.connectionTimeout(Duration.ofMillis(clientConnectionTimeout))
.build())
.overrideConfiguration()
.toBuilder()
.retryPolicy(RetryPolicy.builder().numRetries(NUM_RETRIES).build())
.apiCallAttemptTimeout(Duration.ofMillis(clientRequestTimeout))
.build();
}
...
...
return getInputStream(s3Client.getObject(getGetObjectRequest(storageKey)), isZip);
...
private InputStream getInputStream(ResponseInputStream is, boolean isZip)
throws IOException {
InputStream s3InputStream;
if (isZip) {
ZipInputStream zis = new ZipInputStream(is);
ZipEntry zipEntry = zis.getNextEntry(); // There should be only one entry in the ZIP file

log.debug("getReader: Found zip entry {}", zipEntry.getName());

s3InputStream = zis;
} else {
s3InputStream = is;
}
return s3InputStream;
}
```
The error I see:

```

The question is - why do I see something about the future if I do not use an async client?
How can I correctly get the response and use InputStream here? I can't see any wait/join function to wait

スタックトレースの255行目で特定されている S3EncryptionClient.getObject から始め、レポートに示されているラップされた S3Client と S3AsyncClient の設定を比較してください。提供されたクライアント設定でリクエストを再現し、同期呼び出しがなぜ headersFuture エラーに到達するのかを特定してください。完了の条件は、サポートされている response/InputStream の使用方法、または確認済みのクライアントの不具合が確立されることです。
