AWS SDK 2.x issues in PUTOBJECT request. Unable to add headers

Question

We recently migrated from AWS SDK 1.x to 2.x for Java and put operation for AWS S3 is not happening. S3 bucket is encryption enabled ( using AWS KMS key).

Below is the code I am trying to use but I am getting error mentioned below that

Server Side Encryption with AWS KMS managed key requires HTTP header x-amz-server-side-encryption : aws:kms (Service: S3, Status Code: 400, Request ID: xxx, Extended Request ID: xxx/rY9ydIzxi3NROPiM=)

Update : I figured it out myself. So anyone who wants to benefit to connect to AWS S3 bucket using KMS key and AWS SDK 2.x for Java use the below code it should work

Map<String, String> metadata = new HashMap<>();
    metadata.put("x-amz-server-side-encryption", "aws:kms");
    PutObjectRequest request = PutObjectRequest.builder()
            //.bucketKeyEnabled(true)
            .bucket(bucketName)
            .key(Key)
            .metadata(metadata)
            .serverSideEncryption(ServerSideEncryption.AWS_KMS)
            .ssekmsKeyId("arn:aws:kms:xxxxx")
            .build();
    File outputFile = new File("filename");
    try (PrintWriter pw = new PrintWriter(outputFile)) {
        data.stream()
                .forEach(pw::println);
    }
      awsS3Client.putObject(request, RequestBody.fromBytes(String.join(System.lineSeparator(),
            data).getBytes(StandardCharsets.UTF_8)));
