UnhandledPromiseRejectionWarning: SequelizeConnectionError: Client does not support authentication protocol requested by server; consider upgrading MySQL client
이런 오류가 생기는데, 어떤게 문제인지 모르겠습니다.
원래 강의대로라면 crawler schema에 table이 생겨야하는데, 위 오류가 발생합니다.
mysql 설치시 validation을 설치했는데 그거 때문에 생긴 문제일까요?
코드는 다음 코드에서 돌렸습니다.
