DO Spaces: ERROR InvalidDigest when s3:nodejs_sdk:putObject with ContentMD5 provided

Hi,

I wish to use ContentMD5 to insure integrity check for putObject and getObject.

But Spaces always response 400:InvalidDigest when ContentMD5 supplied.

The Spaces client I’m using is https://www.npmjs.com/package/aws-sdk

and following is the code for putting object

  params =
    Body: content
    ContentMD5 : crypto.createHash('md5').update(content).digest("hex")
    Bucket: S3_BUCKET_PARAMS,
    ContentType : contentType || "application/json"
    Key: remotePath

  log "[putString] params:", params

  S3Client.putObject params, (err, data) ->
    if err?
      log "[putJsonObject] ERROR：#{err}"
      return callback(err)

    log "[putJsonObject] data：", data
    return callback null, data
  return

---

and following is the log

-->
 [putString] params: { Body: '{"haha":"nothing"}',
  ContentMD5: 'e829496f87c60b176b2f288020648348',
  Bucket: 'aaa-bbb',
  ContentType: 'application/json',
  Key: '11111/2019/11/09' } +0ms
