Fatal Error undefined method WC_Order::get_id()

Hi

If anyone can help please.

Problem
========
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.
