Unable to run a backup

When I try to keep running a back I keep getting the following error:
Backup failed: Unexpected end of JSON input while parsing empty string

What error do you get? All works in my test:

I am getting: “Unexpected end of JSON input while parsing empty string”

Thanks for the report. The issue was how empty files/macros are handled by the backup. The issue is fixed with 10.0.285.
