Payload Cloud and cloud-storage plugin, original file not uploading

I've set up the cloud-storage plugin in my Payload Cloud install with GCS. This works fine locally, but while the crops are working as expected on Cloud, the original files are uploaded "empty".

In the screenshot attached, the first image

was added in my local instance. Both the original jpg and the crop are uploaded fine.

The second one though,

, was created on the Payload Cloud instance, and you can see that the original has a size of 0.

The same issue occurs with non-image files like videos, they show up in my GC bucket with a size of 0 (on Payload Cloud, works fine locally).

Given I cannot reproduce the issue anywhere else than in Payload Cloud, I'm a bit stomped on how to investigate this further, so any help would be greatly appreciated! 🙏

So I added some logs to see what was being passed in the beforeChange hook of my media collection (which is how the cloud-storage "intercept" the files:

), and found that

looks like this on Cloud:

file: {
  name: 'arkan-torgadoro.jpg',
  data: <Buffer >,
  size: 374543,
  encoding: '7bit',
  tempFilePath: '/workspace/tmp/tmp-1-1683612139296',
  truncated: false,
  mimetype: 'image/jpeg',
  md5: 'e3e13c5fa3565aa14ee756a415592d5d',
  mv: [Function: mv]
}

Locally, where it works,

looks like this:

data: <Buffer ff d8 ff e0 00 10 4a 46 49 46 00 01 01 00 00 01 00 01 00 00 ff db 00 43 00 08 06 06 07 06 05 08 07 07 07 09 09 08 0a 0c 14 0d 0c 0b 0b 0c 19 12 13 0f ... 374493 more bytes>,

That explains the empty file in the GCS bucket, now onto figuring out why the req is like this. 🔍

I looked into the

object in the

hook, the buffer's already empty there.

Hmmm so I took a look at how the

does things, and there's this part that isn't present in

:

const fileBufferOrStream: Buffer | stream.Readable = file.tempFilePath
          ? fs.createReadStream(file.tempFilePath)
          : file.buffer

Could that be it? 🤔
