I follow your steps to run this demo. I finished adding process template and creating an order. When sale account click 'Start' button. It showed error 'nil is not a symbol nor a string', but refresh browser and the button's text 'Continue' and after click 'Continue'. it showed error 'nil is not a symbol nor a string' again. So how I can do to finish that workflow. Thanks
