"Area code is not set" when trying to send emails

Question

I am trying to send emails programmatically on Magento 2.4.4-p5 using the TransportBuilder, but I get an exception: Area code is not set, even if I set it under the setTemplateOptions method.

This is the content of my custom method used to send emails that is added in a helper file.

        $sender = ['email' => '[email protected]', 'name' => 'Domain'];
        $vars = [
            'message' => 'test here'
        ];
        $this->transportBuilder
            ->setTemplateIdentifier('test_template')
            ->setTemplateOptions(['area' => 'frontend', 'store' => 0])
            ->setTemplateVars($vars)
            ->setFrom($sender)
            ->addTo($toEmail);

        $transport = $this->transportBuilder->getTransport();
        $transport->sendMessage();

A workaround would be to set the area as GLOBAL, but then the email template is not to be found.

Is this a known issue? Am I missing something?

Thank you.

Answer 1

Include this into your code is like this.

use Magento\Store\Model\ScopeInterface;
use Magento\Framework\App\Area;

........... ...........

$storeScope = ScopeInterface::SCOPE_STORE;
$transport = $this->transportBuilder
           ->setTemplateIdentifier('test_template')
           ->setTemplateOptions([
               'area' => Area::AREA_FRONTEND,
               'store' => YOUR_CURRENT_STORE_ID,
            ])
           ->setTemplateVars($vars)
           ->setFrom($sender)
           ->addTo($toEmail);

Answer 2

we can use it as 'area' => \Magento\Framework\App\Area::AREA_FRONTEND

the below code had worked for me,hope it helps

$storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;
        $templateOptions = [
            'area' => \Magento\Framework\App\Area::AREA_FRONTEND,
            'store' => $storeId
        ];
        $transport = $this->transportBuilder->setTemplateIdentifier($templateId, $storeScope)
            ->setTemplateOptions($templateOptions)
            ->setTemplateVars($templateVars)
            ->setFrom($from)
            ->addTo($toEmail)
            ->getTransport();
        $transport->sendMessage();
