강사님 소스랑 똑같이 따라쳤는데 제목과 같은 에러가 납니다. TypeError: Cannot read property 'passport' of undefined at SessionStrategy.authenticate (D:\z3-develope\slack-socket\backend

main.ts에 아래 추가해주고 해결했습니다. 세션이 없어서 난 에러인데.. 신기하네요 다른분들은 괜찮았나요..?? import session from 'express-session' ; app . use ( session ({ secret : 'secret' }));

음 아직 화면이 없어서 포스트맨으로 보냈는데 에러메세지로 보아서는 패스포트를 못읽어오는게 문제인것같기는 하지만... 완벽하게 따라치지 못했을 가능성도 충분하니 좀 더 알아보겠습니다.

tsconfig.json에 esModuleInterop true인가요? import는 어덯게 하셨나요?
