Unable to do CompleteMultipart to s3

[aravinds502]

Hello Guys,

I'm trying to do the "CompleteMultipartUpload" using the java restTemplate as follows, and I see below errors. Here my endpoint is pointing to s3proxy service, that was configured to AWS-S3.

 CompleteMultipartUpload requestBody = new CompleteMultipartUpload(
                parts.stream().map(part -> new CompleteMultipartUpload.Part(part.getPartNumber(), part.getETag()))
                        .sorted(Comparator.comparingInt(CompleteMultipartUpload.Part::getPartNumber)).collect(Collectors.toList()));

        HttpEntity<CompleteMultipartUpload> requestEntity = new HttpEntity<>(requestBody, headers);
        try {
            ResponseEntity<Map> response = restTemplate.exchange(uri, HttpMethod.POST, requestEntity, Map.class);
            log.info("Completed multipart upload :'{}'", response.getBody());
        }catch (Throwable e) {
            throw new MultipartUploadFailureException("Error completing multipart upload for uploadId "
                    + uploadId + "at path " + path, e);
        }

Please let me know what is going wrong.

Thanks
