Commit-archive location ftp stops working after some commits

Hi Vyos Devs,

I noticed that on last 1.4 buildings the commit-archive stops working after some commits, below the issue outputs:

Config applied:
vyos@lab:~$ show configuration commands | grep ftp
set system config-management commit-archive location ‘ftp://admin:pwd@

Issue when trying to save manually:
vyos@lab# save ftp://admin:pwd@
