🔎 Isolate the bug

• [X] I have confirmed this occurs in the most recent version of WordPress, WooCommerce, and Facebook for WooCommerce.
• [X] I have confirmed this occurs when only WooCommerce and Facebook for WooCommerce are active and when using a default WordPress or WooCommerce theme.

✍️ Describe the bug

Uncaught Error: Call to a member function get_name() on string in /plugins/facebook-for-woocommerce/includes/Products.php:1115

When lines 1112-1120 are commented out in Products.php sync runs fine.

It looks like strtolower( $attribute->get_name() ) === $key ) the attribute object is not being passed correctly.

🚶‍♀️ Steps to reproduce

1. Try to Synchronise products
2. Failure to Synchronise Products

✔️ Expected behavior

Product sync should update all products
