How to feed a pack Stream to AWS S3 SDK v3?

[ngervasi-cosa]

Hi,
I'm trying to stream a tar directly to AWS S3 using SDK v.3 like this:

`const readable = tar.pack("${path}/${dirName}");

const pipeline = readable

    .pipe(createGzip())

    .pipe(await uploadStream(readable, s3KeyName,config.attachmentsStorageClass));`

But unfortunately the SDK is checking the stream using instanceof and returns this error:

"Body Data is unsupported format, expected data to be one of: string | Uint8Array | Buffer | Readable | ReadableStream | Blob;.".

tar.pack returns a Pack object, is there any way to convert it to ReadableStream?

It used to work fine in SDK v.2 but with v.3 is broken.

Try using a PassThrough() stream to satisfy the AWS SDK. Instantiate a new (node:stream).PassThrough() and pipe to it after createGzip(). Then give the PassThrough stream to the AWS SDK.
