'int' object has no attribute 'execute' [544][5009]

I tried using the incremental backups for the first time today.
I was able to create exactly one, after I tried to backup another, for any other user, I keep getting the error:
‘int’ object has no attribute ‘execute’ [544][5009]

this occurs regardless of the databases option being checked. Any idea what that means or how to resolve it ?
Is there a way to manually trigger incremental backups from the CLI ?

cyberpanel is updated?
