Can't create viable password hashes

I recently discovered that I can no longer create viable password hashes for use in /etc/dovecot/dovecot.passwd. So far, I've been using the following command done by root:

doveadm_cmd pw -s SHA512-CRYPT -u joe -p mypassword

This creates something that looks legit, but dovecot won't accept it. I've been using my own solution for allowing users to change their dovecot passwords (https://gitlab.com/DavidGriffith/dovepasswd) and this is how it generates the hashes. Is there a better way of going about this?
