This workaround was removed.
You need to assign the helper to use in your nftables ruleset.
ct helper ftp-standard {
type "ftp" protocol tcp
}
And then, from a prerouting chain:
tcp dport 21 ct helper set "ftp-standard"
You might need to do this from output too if you need
this to work from the machine itself as well.
