Write to R2 with ReadableStream

Im trying to write a ReadableStream to R2, however, I cannot pass a stream to the r2

.put

.put

without giving it a fixed size first, so I am piping an email objects stream to a

FixedLengthStream

FixedLengthStream

as so:

let { readable, writeable } = new FixedLengthStream(message.rawSize);
message.raw.pipeTo(writeable);

let { readable, writeable } = new FixedLengthStream(message.rawSize);
message.raw.pipeTo(writeable);

and then saving it to R2 as follows:

await env.BUCKET_NAME.put(identifier, readable);

await env.BUCKET_NAME.put(identifier, readable);

Im seeing the entry

identifier

identifier

in my R2 bucket, however the content is empty.

message.rawSize

message.rawSize

is showing the number of bytes I would expect.

Am I using the stream pipes wrong?

Thank you
