Invalid argument supplied for foreach

What WordPress, PHP and Simple SMTP versions are you using?
e.g. WordPress 5.6, PHP 7.3, Simple SMTP 1.0.0. The more, the better.

• WordPress 5.8.3
• Simple SMTP 1.3.1

Describe the bug
In src/mail/class-mail.php on line 13

Steps to reproduce

1. Enable WP_DEBUG and WP_DEBUG_LOG
2. Enable debug log in Simple SMTP
3. Send a test email
4. Check debug.log for errors

Line 13 of class-mail.php is an import statement?

use wpsimplesmtp\Log;

I'm also not able to replicate the bug on my test copy of 1.3.1. Perhaps a screenshot of the error will help to collaborate the issue? There's a foreach statement in class-mail.php on line 135 that I'm wondering it might be referring to.

Sorry, I made a typo. The error is on line 135.

Sorry, I made a typo. The error is on line 135.

No worries - looks like the error will be coming from the attachment segment. Will run some trials when time permits.

It actually didn't strike me that an issue on line 13 could've been 135... Ahh, it's been a long day.

I can't reproduce that anymore.

I still get some warnings on a website using the latest available version of WordPress (6.2) and Simple SMTP (1.3.2.2).

On this website, the logs are enabled.

Here are the related warnings:
