Fatal Error in class-wc-gateway-stripe.php

Hi
After a call to stripe to process a card payment the screen is displaying the “There has been a critical error on this website” message. The payment is accepted, the order status is left at ‘pending’. All processing is stopped at this point. This is occurring at irregular intervals; not with every order.

What does ” PHP Fatal error: Uncaught Error: Call to undefined method WC_Order::get_id() in /home/…/public_html/donate/wp-content/plugins/woocommerce-gateway-stripe/includes/class-wc-gateway-stripe.php:981″ mean?

I need to try and fix this without any plugin updates or downtime as the site currently has heavy traffic and cannot afford any downtime if plugins updates fail.

Can I comment out this line ” clean_post_cache( $order->get_id() );” ?

Thank you
Annie
