12.1.1 vs 11.5.4 cli syntax

I have a script that runs a backup and i just started using my first 12.1.1 OS from 11.5.4. On 11.5.4 I used this line to create a config file backup. tmsh save sys config one-line file FILENAME

Now on 12.1.1 I get this error with the same command. Data Input Error: "passphrase" passphrase should be provided or use the no-passphrase option

Tabbing through the options it looks like I cannot specify a filename and use the no-passphrase at the same time. Any ideas how I can accomplish the above config line?

Thanks!
