How to send an Order Confirmation email from script

Question

When I try sending an email from the root script in Magento I get the below error:

Fatal error:  Uncaught exception 'BadMethodCallException' with message 'Missing required argument $debugHintsPath of Magento\Developer\Model\TemplateEngine\Plugin\DebugHints.' in

Below is the code which I have used:

$orderid = '000000003';
$order = $obj->create('Magento\Sales\Model\Order')->loadByIncrementId($orderid);
// print_r($order->getData());

$obj->create('Magento\Sales\Model\Order\Email\Sender\OrderSender')->send($order,true);

Answer 1

try using

$orderid = '000000003';
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$order = $objectManager->create('Magento\Sales\Model\Order')->loadByIncrementId($orderid);
$objectManager->create('Magento\Sales\Model\OrderNotifier')->notify($order);
