Scripted backup of evolution on F43 KDE error

Since upgrading to F43 KDE F42 KDE I’m receiving the following error when my evolution backup script runs:

“Failed to verify the backup file “” , the archive is broken.”

I’m using the same script which calls /usr/libexec/evolution/evolution-backup with the --backup option. My script still creates the backup file as always but I get the above error and don’t understand why.

Any help would be appreciated.
