I am having issues with the Catalook checkout erroring out when creating orders and I'm having a hard time finding good information about the store and common issues/answers. The error that I am getting is a null reference in the AssignSerialNumbers() method. The site uses DNN v7.4.1 and the catalook store version is 7.1.2. I inherited this DNN project and am still getting used to all of the options and settings in DNN. error screenshot with full stack trace
Any advice would be appreciated.
Thanks
