질문있습니다

카카오로 로그인 하기 부분에서 

const passportConfig = require("./passport/index");

 passportConfig();
위에 두줄 코드를 추가하면

C:\Users\youngman\Desktop\nodejs-book-master\nodejs-book-master\ch9\lecture\node_modules\passport-local\lib\strategy.js:47

if (!verify) { throw new TypeError('LocalStrategy requires a verify callback');} ^

TypeError: LocalStrategy requires a verify callback at Strategy

같은 에러가 발생합니다 어떻게 해결해야 하나요..?

코드 두줄을 입력하지 않으면 작동이 서버가 켜집니다
