What steps will reproduce the problem?

The bug occurs when trying to use swiftMailer to send emails in PHP 7.4.x. Works fine in PHP 7.3.

The config:

'mailer' => [
                        'class' => 'yii\swiftmailer\Mailer',
                        'viewPath' => '@common/mail',
                        'transport' => [
                              'class' => 'Swift_SmtpTransport',
                              'host' => '***',
                              'username' => '***',
                              'password' => '***',
                              'port' => 465,
                              'encryption' => 'ssl',
                        ],
                        'useFileTransport' => false,
 ],

The code sample that generates the fatal error:

Yii::$app->mailer
     ->compose('userSignUp')
     ->setFrom('<email_address>')
     ->setTo('<email_address>')
     ->setSubject('Testing ...')
     ->send();

What is the expected result?

Should send an email to the recipient, optionally include HTML or text-only view templates.

What do you get instead?

PHP error -

Like that stack says it's a problem in your 3rd party email validator and here is the PR fixing it. Update your software frequently.

Thank you for pointing out the other post. I was considering editing the line generating the error to check/bypass null values, though I was not sure whether the variable was designed to ever be null and allowing the code to continue with null would cause issues. Also, I am concerned that my edits will get wiped out if the codebase is ever updated.

I will continue with the edit for now.
