Set TWILIO_DEBUG_TO= to: TWILIO_DEBUG_TO=null and you'll be good to go.

It's getting caught up here in the sendSmsMessage() method:

        $debugTo = $this->config->getDebugTo();

        if ($debugTo !== null) {
            $to = $debugTo;
        }

is this only in debugging? What about in production? it seems we need to set it to null in production

Set TWILIO_DEBUG_TO= to: TWILIO_DEBUG_TO=null and you'll be good to go.
