    We are seeing that some WooCommerce Subscription renewals are hitting a fatal error with Cartflows when using the Google Tracking data feature. Here is the error:

    [23-Feb-2021 15:20:10 UTC] PHP Fatal error: Uncaught Error: Call to a member function get_cart_contents_total() on null in /public_html/wp-content/plugins/cartflows/classes/class-cartflows-tracking.php:135

    Would adding a check like this if the order is a renewal resolve the issue?

    /wp-content/plugins/cartflows/classes/class-cartflows-tracking.php
    line 135

    
$order             = wc_get_order( $order_id );
if ( function_exists( 'wcs_order_contains_renewal' ) ) {
	if ( wcs_order_contains_renewal( $order_id ) == true ) { 
		return;
	}
}
$cart_total        = WC()->cart->get_cart_contents_total();

    Hello @contemplate

    Thank you for getting in touch with us!

    Actually, the code which you have mentioned will work then the order is placed from the Checkout page and the user has completed the order on the thank you page.

    But will not work while making the automatic subscription renewal payment. So, in order to get more clarification, can you please open a support ticket from our website so that one of the developers will take a look at it.

    I hope this helps you.

    I am looking forward to hearing from you.

    Yes I created ticket 1763 before I created this patch if you want to add this to the ticket.

    Yes I that is correct the code I added (above) should skip the rest of the function if it is a renewal payment since there isn’t a “cart” instance and so the get_cart_contents_total function won’t be run which is the reason for the error.
