Vyatta-cfg-system: "add system image" does not work with file path


I have faced a situation today, I am trying “add system image /etc/ulak/vyos-1.2.iso” command with existing iso file, but the response is shown as below.

–username use username for HTTP auth (optional)
–password use password for HTTP auth (optional)
I looked commits, I guess, there is a bug occured after commit “771e535725cee0c01a80a71717afce85d7efcc70”. Because I can use this command before the pull updated repositories. Maybe I miss something about using this command. Any idea or suggestion? Thanks
