PHP error messages (undefined path & type bool)


I’m receiving a couple of error messages in my debug file. I’ve only just noticed them but they go back to February this year at least.

These are the messages:

PHP Notice: Trying to access array offset on value of type bool in /home/****/public_html/****/wp-content/plugins/auto-post-thumbnail/includes/class-plugin.php on line 555

PHP Notice: Undefined index: path in /home/****/public_html/****/wp-content/plugins/auto-post-thumbnail/includes/class-plugin.php on line 555

Any idea what’s causing them? Thanks in advance.
