해결방법

application properties에 설정이 제대로 되지 않았을 가능성이 있습니다. 

저의 경우에는 spring.security.oauth2.client.provider 관련 설정이 빠져서 발생한 오류였습니다.

아래와 같은 설정 후 정상으로 작동하는걸 확인했습니다.

#auth
spring.security.oauth2.client.registration.kakao.client-id = [rest api key]
#spring.security.oauth2.client.registration.kakao.client-secret = [secret]
spring.security.oauth2.client.registration.kakao.redirect-uri=http://localhost:8080/login/oauth2/code/kakao
spring.security.oauth2.client.registration.kakao.authorization-grant-type=authorization_code
