docusign getDocument返回带有签名问题的空白pdf

Question

iam使用服务器端的docusign包，允许我的客户签名并下载签名文件。在如何客户完成签名后，我试图存储文档，但pdf是空白的。我的账户在生产中。知道为什么吗？

  let dsApiClient = new docusign.ApiClient();//simple init
    dsApiClient.setBasePath(args.basePath);
    dsApiClient.addDefaultHeader('Authorization', 'Bearer ' + args.accessToken);

  let envelopesApi = new docusign.EnvelopesApi(dsApiClient),
      results = await envelopesApi.getDocument(args.accountId, args.envelopeId, args.documentId, null);
      fs.writeFile('test.pdf', data, 'utf8', (error_file) => {
        console.log(file_name)
      });//simple store binary to my hard drive

可以用流存储pdf

const stream = fs.createWriteStream(tempFilePath, { flags: 'a' });
    stream.on('error', function(err: any) { 
      reject(tempFilePath);
    });
    stream.on('finish', function() {
      resolve(tempFilePath);
    });
    stream.end(data, 'binary');
