Google Cloud Storage - how to receive specific generation of file in Node.JS

I am using @google-cloud/storage for accessing the GCS API. After enabling versioning, I am trying to fetch a specific generation of a file using the following code:

bucket.file(`${name}#${generationId}`).download({
    destination
}).then(() => {
    res.set({
        'Content-Type': 'image/jpeg'
    });
    return res.status(200).sendFile(destination);
})

Where name is the complete object name and generationId contains the number of the generation of the file.

However, if I am executing above code within Google Cloud Functions, I am receiving the following error message:

ApiError: No such object: my-bucket/image-mxmg569kdvnby6z85mi#1522107649220516

I am sure that the file and generation exists, as I have checked it with the JSON API explorer. My guess is that @google-cloud/storage does not support file versioning (yet), the documentation did not contain any information. Does anyone have experience with that?

If you set options.generation when instantiating the File object, it should work! https://github.com/googleapis/nodejs-storage/blob/4f4f1b4043c4f70ee99f051499ac62e893abdde0/src/file.js#L82

bucket.file(name, { generation: generationId })
