            Not all errors have codes, so this is usually empty.

            `CH.003.080` (403) means the organisation in `meta.organisation_id`
            requires two-factor authentication and the caller's session does not
            satisfy it. The caller must set up or use a second factor, or sign
            in through their organisation's SAML single sign-on. Other OIDC
            sign-ins do not count.
