.toBuffer() not working with s3.putObject

When I try to write my generated .docx file to s3, everything goes well. But when I download the file from s3 using the public link, my text editor can’t open it as it is base64 encoded string. If I use packer.toBuffer(doc) instead the s3.putObject is not happy and says he requires buffer or base64 string. Why is toBuffer not valid argument for s3.putObject.

...
// set up doc and packer, doc is generated normally I checked
const documentBuffer = await packer.toBase64String(doc);

s3.putObject(
    {
      Bucket: "my-bucket",
      Key: "my-file.docx",
      Body: documentBuffer,
      ACL: "public-read",
      ContentEncoding: "base64",
      ContentType:
        "application/vnd.openxmlformats-officedocument.wordprocessingml.document"
    },
    resp => {
      console.log({ resp });
    }
  );

I had the same issue (https://github.com/dolanmiu/docx/issues/379).

You can wrap the “buffer” and it will work:

buffer = await Packer.toBuffer(doc);

s3.putObject({
    Bucket: "my-bucket",
    Key: "my-file.docx",
    Body: Buffer.from(buffer), // wrap here
}, (res) => {
    console.log(res);
});
