Hi,
I developed a customized payment extensions and when I click the "go to checkout" button on front-end, it will throw a exception "Object DOMDocument should be created".
I checked the var/log/debug.log file and I got a error message "main.CRITICAL: More than one node matching the query"
I tried to debug it and I got more details like
main.CRITICAL: More than one node matching the query: nodePath=/payment/credit_cards/type,matchedNodeslength=11,rootNamespace= [] []
Can anyone tell me how to debug my extension step by step?
Thank you.
