Trouble finding MailgunTransportFactory class in Laravel 9 project

I’m having issues with my Laravel 9 project. I’m trying to set up Mailgun for sending emails, but I’m running into a problem.

When I attempt to send a test password reset email, I get this error:

Class "Symfony\Component\Mailer\Bridge\Mailgun\Transport\MailgunTransportFactory" not found

I think it might be because I upgraded this project from Laravel 8 to 9 recently. Could it be looking for something in the app directory that isn’t there?

My project uses Jetstream with Inertia.js and Vue.js. I’ve installed the required packages using Composer. Here’s a snippet from my composer.json:

{
  "require": {
    "laravel/framework": "^9.2",
    "symfony/http-client": "^6.0",
    "symfony/mailgun-mailer": "^6.0"
  }
}

Any ideas on what might be causing this issue or how to fix it? I’m pretty stumped.

hey sparklinggem, i had this problem too. check ur composer.json and make sure u have ‘symfony/mailgun-mailer’ listed. if not, run ‘composer require symfony/mailgun-mailer’. then do ‘composer dump-autoload’ and ‘php artisan optimize:clear’. that fixed it for me. good luck!

Have you considered checking your service provider configuration? In Laravel 9, the MailgunTransportFactory should be automatically registered, but sometimes this can get messed up during upgrades.

Take a look at your config/app.php file. Make sure you have Illuminate\Mail\MailServiceProvider::class, in the providers array. If it’s not there, add it.

Also, try running php artisan vendor:publish --tag=laravel-mail to publish the mail configuration files. This might restore any missing components.

If none of that works, you could try manually registering the MailgunTransportFactory in your AppServiceProvider. Add this to the boot method:

$this->app->resolving('mail.manager', function ($manager) {
    $manager->extend('mailgun', function () {
        return new MailgunTransportFactory();
    });
});

Just remember to import the necessary classes at the top of the file. Hope this helps!

I encountered a similar issue when upgrading from Laravel 8 to 9. The problem is likely due to changes in how Laravel 9 handles mail transport factories.

To resolve this, you need to update your config/mail.php file. Look for the ‘mailers’ array and make sure the Mailgun configuration is correct. It should look something like this:

'mailgun' => [
    'transport' => 'mailgun',
],

Also, double-check that you’ve set up your Mailgun credentials correctly in your .env file. You’ll need these lines:

MAILGUN_DOMAIN=your-domain.com
MAILGUN_SECRET=your-mailgun-secret-key

If you’re still having trouble, try clearing your configuration cache with php artisan config:clear and then php artisan config:cache.

Lastly, ensure you’re using the latest versions of the Mailgun packages. You might want to run composer update to get the most recent compatible versions.

Hope this helps solve your issue!
