`UPDATE
                user_password_reset_tokens
            SET used = true
            WHERE
            token = $1::uuid
            AND NOT used
            AND now() at time zone 'utc' < expires_on
            RETURNING *`, [token]
            );
        console.log('verified');

        return usedToken.user_id;
    } catch (err) {
        if (err instanceof errors.QueryResultError)  {
            console.log(err.code);
            if (err.code === errors.queryResultErrorCode.noData) return undefined;
        }

        throw err;
    }
}
