Answer 1

I have no idea but I finished the course just a week ago.
It is a little warning.
Later in the course the code playground's code is broken. Some of them is easy to fix (by changing the Ticket name to the most recent one. Don't worry, you will learn what is Ticket later). And some other code simply doesn't work, it maybe due to the module changed the workflow and I don't have a clear answer.
I managed to complete the course but leave many unanswered question in my mind.
