Backup problem

I have trouble with sheduled backups
Manual full backup runs fine, but sheduled does not make backup with an error

/home/interworx/bin/scheduled-backup.pex --execute=15 # c****.com -full - daily
To: root@panel.*****.com
Model_Scheduled_Backup with primary id "15" does not exist.


Using NFS
In System Health Fively CRON Stuck NOT OK
Panel version 5.0.12
