我使用以下代码压缩并上传一个对象到s3：

let data: string | Buffer = JSON.stringify(rules);
  let contentType = "application/json";
  let encoding = null;
  let filename = `redirector-rules.json`;
  if (format === "gz") {
    contentType = "application/gzip";
    encoding = "gzip";
    filename = `redirector-rules.gz`;
    const buf = Buffer.from(data, "utf-8");
    data = zlib.gzipSync(buf);
  }

  // res.end(data);
  // return res.status(200).send(data);
  await s3.upload(filename, data, contentType, encoding);

我假设这是正确的工作，因为当我使用aws s3 cp命令下载结果文件时，它工作得很好，我能够在我的机器上解压缩它。此外，可能不相关的事实是，如果我通过s3的conole下载，我的系统无法解压缩它，它可能会损坏或截断。
在另一端我有一个lambda代码读取get对象并试图解压缩它：

const getRules = async (rulesCommand: GetObjectCommand): Promise<Config> => {

    const resp = await fetchRulesFile(rulesCommand);
    const data = await parseResponse(resp, rulesCommand);

    return data;

};

const fetchRulesFile = async (rulesCommand: GetObjectCommand): Promise<GetObjectCommandOutput> => {
  try {
    console.log(`Retrieving rules file with name ${rulesCommand.input.Key}`);
    const resp = await client.send(rulesCommand);
    return resp;
  } catch (err) {
    throw new Error(`Error retrieving rules file: ${err}`);
  }
};

const parseResponse = async (resp: GetObjectCommandOutput, rulesCommand: GetObjectCommand): Promise<Config> => {
  const { Body } = resp;
  if (!Body) {
    throw new Error("No body in response");
  }

  let data: string = await Body.transformToString();

  if (rulesCommand.input.Key?.endsWith(".gz")) {
    console.log(`Uncompressing rules file with name ${rulesCommand.input.Key}`);
    try {
      data = zlib.gunzipSync(data).toString("utf-8");
    } catch (err) {
      throw new Error(`Error decompressing rules file: ${err}`);
    }
  }

  return JSON.parse(data) as Config;
};

但我一直收到这个错误：Error: incorrect header check
