我有不同的对象生成文件保存在S3中。每个对象调用以下函数来保存文件。
我有以下问题，只有少数对象。对象要么总是保存文件，要么永远不能保存文件。

/**

     * @return the eTag of the uploaded file
     * @throws IOException If an error occurs during the file upload

    public String upload(String bucketId, String key, InputStream inputStream, Map<String, String> metadata) throws IOException {
        LOG.info("Upload file {} on bucket {} with metadata: {}", key, bucketId, metadata);
        CreateMultipartUploadRequest.Builder builder = CreateMultipartUploadRequest.builder();
        if (!this.encryptionAlgorithm.equalsIgnoreCase("none")) {
            builder = builder.serverSideEncryption(this.encryptionAlgorithm);
        }
        CreateMultipartUploadRequest createMultipartUploadRequest = builder.bucket(bucketId)
            .key(key)

        CreateMultipartUploadResponse createMultipartUploadResponse = s3Client.createMultipartUpload(createMultipartUploadRequest);
        String uploadId = createMultipartUploadResponse.uploadId();

        try {
            List<CompletedPart> parts = uploadFileParts(bucketId, key, uploadId, inputStream);

错误是

• • 我们计算的请求签名与您提供的签名不匹配。请检查您的AWS保密访问密钥和签名方法。有关详细信息，请参阅REST身份验证和SOAP身份验证。（服务：S3，状态代码：403，请求ID：79b6c0a2 - 0d74 - 1f30-a4bf-246e9631ccd8，扩展请求编号：无效）**

我验证了，bucket始终是相同的值，输入流数据包含文件的数据，数据成功传输到S3 bucket，key始终是eventsnapshot-21234-7-2021-08-12-1628767690000.jpg。
你已经有这样的问题了吗？
