S3 upload fails with Argument #1 ($user) must be of type OCP\IUser, null given

提供された occ backup:point:upload コマンドで再現し、その後 apps/files_versions/lib/Storage.php の230行目付近と lib/Versions/VersionManager.php の90行目付近を調査します。custom_apps/backup/lib/Service/ExternalFolderService.php の223行目からの呼び出しを追跡し、バックアップをS3外部フォルダーにアップロードしても null IUser TypeError が発生せずに完了することを確認します。

I can't upload backup archive (packed,compressed,encrypted) to s3, that is mounted as external storage and accessible in files interface. Folders are successfully created on s3, but files upload fails. Looks it tries to upload with a user owner in metadata, as seen in error message, that is inexistant as called from CLI.

NC 24.0.6 with official docker image. Backup 1.1.3.

$ ./occ backup:point:upload 20221018174455-full-xxxx --remote="amazon::external::xxxxxxxxxxxxxxxxxxxxxxxxxxx" -vvv
