docx.Packer.toBuffer returns uint8Array and not Buffer in node

Hi

I run this code. Generating a buffer and and writing it with express as a downloadable file.

  const buffer = await docx.Packer.toBuffer(doc)
  console.log(Buffer.isBuffer(buffer))
  res.status(200).end(buffer)

However the generated buffer is really an uint8Array (and Buffer.isBuffer writes false) so the res.end call fails with the following error:

2020-05-12 00:12:07 TypeError [ERR_INVALID_ARG_TYPE]: The "chunk" argument must be of type string or an instance of Buffer. Received an instance of Buffer
    at ServerResponse.end (_http_outgoing.js:753:13)
... call stack for my application removed...

If I however changes the array to a buffer with Buffer.from is everything working and Buffer.isBuffer returns true

  const arr = await docx.Packer.toBuffer(doc)
  const buffer = Buffer.from(arr)
  console.log(Buffer.isBuffer(buffer))
  res.status(200).end(buffer)
