- caught (in promise) SyntaxError: Unexpected token '<', "<!doctype "... is not valid JSON
- to load resource: the server responded with a status of 500 (INTERNAL SERVER ERROR)
DB연결때문에 그런건가 싶어서 DB연결 코드를 지워보기도 하고,
JSON이 chat GPT 통해서 오류를 고치려 노력하는데도 불구하고,
계속해서 콘솔에서 이런 오류가 뜹니다.ㅠㅠ
json 문제일 것 같아서 json설치를 새로 해보았으나 해결이 되지 않아요.
하지만, 코드에 어떤 문제가 있는지 잘 모르겠어요
작성한 코드 및 에러 메세지
Tip 1) </> 아이콘을 눌러 코드박스를 만들어 보세요.
Tip 2) Ctrl+A(맥의 경우 Command+A) 단축키로 코드를 한 번에 선택할 수 있어요!
