I think that this is due to pinentry program (it complains that there's no suitable device, tty, to ask passphrase).

Well, older GnuPG was more friendly in those situations where a programmer wants to feed passphrase input by other method.

IIUC about your intention by using --passphrase-fd, what you need here is an option --pinentry-mode=loopback (not to use an external pinentry program).

Hope this helps,
