기본적으로 웹팩에서 모듈을 로드하는 과정에서 오류가 있는 경우에 발생함.

 

내 경우는 Redux Toolkit을 사용하고 있었고, 

빠른 수정으로 import할 때, "@reduxjs/toolkit"에서 가져와야 하는데 어쩌다가 다른걸 선택해서 아래처럼 내부에 있는 것을 import하는 경우가 있었음.

import { createAction } from '@reduxjs/toolkit/src/createAction';

이걸 아래처럼 바꿔주면 해결됨.

import { createAction } from '@reduxjs/toolkit';
