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

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

Reproduce with the provided occ backup:point:upload command, then inspect apps/files_versions/lib/Storage.php around line 230 and lib/Versions/VersionManager.php around line 90. Trace the call from custom_apps/backup/lib/Service/ExternalFolderService.php line 223 and verify that uploading a backup to the S3 external folder completes without the null IUser TypeError.
