Heroku Scheduler выдает эту ошибку в скрипте (приложение Django)

Question

Ошибка заключается в следующем:

  File "manage.py", line 10, in <module> 
    execute_from_command_line(sys.argv) 
  File "/app/.heroku/python/lib/python2.7/site-packages/django/core/management/__init__.py", line 364, in execute_from_command_line

Да, вы можете сказать мне, установить пакет (?), Но уже в приложении, во всех других процессах я могу отправлять электронные письма, кроме этогоscript!

Код отправки электронной почты:

message = EmailMessage("xxxx", "xxxx", "xxx@xxx",
                               ["xxxx@xxxx"])
message.attach('xxx.csv', csvfile.getvalue(), 'text/csv')
message.send()
logger.info(len(send_orders))

Я запускаю сценарий в стандартном режиме 1X Dyno

Правка для кода команды:

class Command(BaseCommand):
    def handle(self, *args, **options):
        date_start = timezone.now() - relativedelta.relativedelta(days=1)
        csvfile = StringIO.StringIO()
        states = ['ORDER_DELIVERED', 'ORDER_DELIVERED_UNRATED', 'ORDER_DELIVERED_RATED']
        send_orders = Order.objects.filter(state__in=states, date__lt=date_start, erp_sent=False).order_by('id')
        file_rows = ["order", "client", "Fecha", "response ERP"]
        csvwriter = csv.writer(csvfile)
        csvwriter.writerow(file_rows)
        for order in send_orders:
            try:
                odoo_manager = OdooERPManager()
                send_bill_erp = odoo_manager.send_sale(order)
                if str(send_bill_erp).find('creada') > 0:
                    order.erp_sent = True
                    order.save()
                else:
                    csvwriter.writerow([order.id, order.client, order.delivery, send_bill_erp])
            except Exception as e:
                csvwriter.writerow([order.id, order.client, order.delivery, e])
        logger.info(len(send_orders))
