인프런 커뮤니티 질문&답변

라우터 전부 있고 axios baseUrl = http://localhost:3065 로 했는데 프론트서버 킬때 웹페이지 화면은 나오는데 ECONNREFUSED 에러가 뜨네요. 이 에러의 원인은 무엇인가요? (LOAD_MY_INFO_FAILURE, LOAD_POSTS_FAILURE 액션에서 data undifined error가 나와서 둘다 액션을 error: err.name으로 바꿨습니다. name으로 안하면 data undefined error만 나오더라구요.) 아 그리고 백서버도 켜져있습니다.

LOAD_MY_INFO_FAILURE 부분 콘솔 에러입니다.
