Default Symfony Logo attached to all emails

The string "logo.png" is only in TestEmailBuilder.php. I think the problem is something local on your site.

Yes I did see that it is only in the test.php but for some reason it has started showing up in all emails. I have not made any changes to the Symfony mailer config.

Emails are sent through eca as html and mass contact message.

See attached screenshots.

Previous messages do not have the attached logo.

I have been wrestling with this for a week. The logo issue goes away if I downgrade an lock module at 1.5. Now having an config sync issue with the mailer transport sub module not being installed. Ideally it would be great to find a solution to the default logo and move back to the latest release.

I am using ECA HTML Email to send mail. All emails have the default logo attached. There is no customization beyond adding Sendgrid SMTP as the mail server. Let me know what additional info I can provide to help test.

Line 51 of TestEmailBuilder.php - commenting out line 61 and 62 is the only thing that removes the logo from my (non-test) emails. Please advise.

/**
* {@inheritdoc}
*/
public function build(EmailInterface $email) {
$logo = \Drupal::service('extension.list.module')->getPath('symfony_mailer') . '/logo.png';
$logo_uri = \Drupal::service('file_url_generator')->generateString($logo);

// - Add a custom CSS library, defined in symfony_mailer.libraries.yml.
// - The CSS is defined in test.email.css.
// - Set variables, used by the mailer policy defined in
// symfony_mailer.mailer_policy.symfony_mailer.test.yml.
// - Add an attachment.
$email->addLibrary('symfony_mailer/test')
// ->attach(Attachment::fromPath($logo_uri, isUri: TRUE))
// ->setVariable('logo_url', $logo_uri)
->setVariable('day', date("l"));
}

}

}

Same problem using ECA HTML Email too
