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

Reproducir con el comando occ backup:point:upload proporcionado y, después, inspeccionar apps/files_versions/lib/Storage.php alrededor de la línea 230 y lib/Versions/VersionManager.php alrededor de la línea 90. Seguir la llamada desde custom_apps/backup/lib/Service/ExternalFolderService.php, línea 223, y verificar que la carga de una copia de seguridad en la carpeta externa de S3 se complete sin el null IUser TypeError.

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
