인프런 커뮤니티 질문&답변

JSON 표기법 실습을 진행중이다. 아래 명령어를 실행하는데, 에러가 난다. json 문자열 속 쌍따옴표를 백슬래시로 이스케이프 하는게 안 먹혀서 그런 것 같다. 견문이 부족하여 스스로 해결 못 하였다. GPT가 알려주는 대로도 해봤지만 따옴표가 문자열에 들어가지 않는다. 문자열이 어떻게 입력되는지는 아래에 있는 에러코드에서 확인 가능하다. 혹시나 답을 알 수 있을까 질문한다.

window 환경, 스프링부트 3.5.2, jdk 17이고, 인텔리제이에서 실습중이다.

intellij 로컬 터미널과, git bash등에서 아래 명령어를 실행했으나 실패하였다.
