제가 이 강좌로 실습을 한번 하고 다시 복습겸 공부하고있는데요
새로운 웹사이트를 개발하려고 part2에 진입해서 몽고 db를 연결했는데 아래와 같은 에러가 떴어요
에러:(node:45836) Warning: Accessing non-existent property 'MongoError' of module exports inside circular dependency
(Use node --trace-warnings ... to show where the warning was created)

에러를 이해하질 못했는데 전에 사용하던 포트는 8000번이고 지금복습할때 사용하는 포트번호는 8080번호입니다.
Cluster0에 2개의 포트가 연결하려고 하니 생긴 에러인가요? 새로 cluster를 만들려고하니 무료가 안되더라구요
