Bug description

After updating to latest Herd version 1.20.1 my mail server stopped working. It starts up fine, but it crashes when sending an email.

Port 2525 is free. Starting mailserver.
Mailserver listening on port 2525

node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^

TypeError: object is not iterable (cannot read property Symbol(Symbol.iterator))
    at /snapshot/herd-mailserver/index.js

Node.js v18.5.0

MAIL_MAILER=smtp
MAIL_SCHEME=null
MAIL_HOST=127.0.0.1
MAIL_PORT=2525
MAIL_USERNAME="Mark"
MAIL_PASSWORD=null
MAIL_FROM_ADDRESS="hello@example.com"
MAIL_FROM_NAME="${APP_NAME}"

Steps to reproduce

I was about to report the same thing, same error:

node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^

TypeError: object is not iterable (cannot read property Symbol(Symbol.iterator))
    at /snapshot/herd-mailserver/index.js

Node.js v18.5.0

It systematically happens after the first email is sent.

I have the exact same error.

Port 2525 is free. Starting mailserver.
Mailserver listening on port 2525
node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^
