I printed the header field and field_id = 90. Any idea?

Looks like libkeepass doesn't support Argon2

libkeepass only supports kdb and kdbx v3. See libkeepass/libkeepass#24

[jleclanche]

Why does it say "and KeePass 2.x (v4) files" then?

I worked around my issue by converting my 4.x db into a 3.1 one, but I guess I'll close in favor of that issue then.
