이부분은 인코딩이 잘못되었다는 이야기로 카카오와 무관한 문제 같구요.

org.springframework.web.client.HttpClientErrorException$Unauthorized: 401 Unauthorized: [no body]

이부분은 액세스 토큰 발급 시, 에러 발생한 것으로
아래와 같은 응답이 전달되었습니다. 액세스 토큰 발급 요청 시, Client Secret을 전달하거나 비활성화하시면 됩니다.

{"error":"invalid_client","error_description":"Bad client credentials","error_code":"KOE010"}

조치에 어려움이 있다면, 아래 내용 참고하시면 좋을 것 같습니다.

안녕하세요. 혹시 어떻게 해결하셨는지 여쭤봐도 될까요… 카카오는 아니구 네이버 api 사용하고 서버에 올리고 호출해보니까 똑같은 에러가 뜨네용…
