> The {{GoogleCloudBucketHelper.google_cloud_to_local}} function now fails with a ValueError, with:
> {noformat}
> ...
> file_size = self._gcs_hook.download(bucket_id, object_id, local_file)
> if os.stat(file_size).st_size > 0:
>     return local_file
> ...
> {noformat}
> The {{os.stat()}} function takes a _path_, but the {{file_size}} var passed in is actually the downloaded bytes from {{GoogleCloudStorageHook.download()}}.
> The error is like:
> {noformat}
