Write files with uid=0

Hi All
When trying to write to tape files with owner root , we get the message
cta-taped: LVL=“ERROR” PID=“2910” TID=“3250” MSG=“In ArchiveMount::reportJobsBatchWritten(): got an exception” thread=“MainThread” tapeDrive=“DRIVE0” mountId=“6” exceptionMessageValue=“filesWrittenToTape: filesWrittenToTape failed: TapeFileWrittenEvent is invalid: diskFileOwnerUid is 0”
Question: can CTA writes on tape files with uid=0?

No, this is explicitly forbidden. All files must be owned by a user account.

Thank you. Your answer helped us a lot.
