네 에러메세지는 아래와 같습니다! (사진) (사진) (사진) (사진) (사진) (사진)

MemberRepositoryTest를 돌리는 과정에서 아래와 같이 에러가 나타납니다.

네 감사합니다. 위와 같이 findUsername으로 작성을 하고 돌렸는데 위와 비슷한 에러를 만나서 해결을 계속하고 있지만 찾지못하였습니다.....

주문내역을 들어갈 때 에러가 났습니다.

ㅠㅠ 늦은시간에 답변 감사합니다!!

안녕하세요 6분정도에서 무한루프관련이 안뜨고 에러가 떠서 질문드립니다.

강사님 해결하였습니다. 감사합니다. member에 아래와 같이 @embedded부분에 @jsonIgnore를 넣으니 해결되었습니다. (사진)
