Error on shop page : Expected WC_Product, got 'false' when generating ViewCategory event.

Hello,

it seems an error is caused on many shop pages. These were picked up by Google Webmaster Tool so this is not just a manually created link.

Example url:
website.com/Shop/page/12/?orderby=price
The error is as follows:
Fatal error: Uncaught Error: Call to a member function get_sku() on boolean in /mnt/env/website/production/public_html/wp-content/plugins/facebook-for-woocommerce/includes/fbutils.php:86 Stack trace: #0 /mnt/env/website/production/public_html/wp-content/plugins/facebook-for-woocommerce/facebook-commerce-events-tracker.php(49): WC_Facebookcommerce_Utils::get_fb_content_ids(false) #1 /mnt/env/website/production/public_html/wp-includes/class-wp-hook.php(298): WC_Facebookcommerce_EventsTracker->inject_view_category_event('') #2 /mnt/env/website/production/public_html/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #3 /mnt/env/website/production/public_html/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #4 /mnt/env/website/production/public_html/wp-content/plugins/woocommerce/templates/archive-product.php(96): do_action('woocommerce_aft...') #5 /mnt/env/website/production/public_html/wp-includes/template-loader.php(74): include('/mnt/env/goedes...') #6 /mnt/env in /mnt/env/website/production/public_html/wp-content/plugins/facebook-for-woocommerce/includes/fbutils.php on line 86

Is this a known issue and is there a fix for this?

This is a new issue, I'll look into adding a fix for the next version. Looks like it happens for ViewCategory pixel events, where one of the products is deleted? I haven't been able to get a repro yet.

Thank you dmitridr, that is appreciated.
It might be that the product is deleted I cannot verify that as of now.

But it seems to be on multiple pages and Google Webmaster tools has encountered multiple of these errors.

We weren't able to repro, but I added logic in v1.6.2 that should prevent an exception there in future versions. Thanks for reporting this!
