We were able to get the console screenshots from a few users and none of them show any errors. I’m not sure if adding the listener for CardInputEventState will help in this case. Per SDK documentation, the CardInputEventState deals with “The state of an input field at the time a card input event is triggered”. In our case, the payment card fields are not shown on the page. If user does not have any fields to type in, I think this event will never get generated.
