REST API 키를 사용해서 server to server 연동을 하고 계신것 같네요.
관련 로그를 보니 REST API 키 노출에 의한 어뷰징을 막기 위해 제공하고 있는 IP 검증에서 문제가 된 것 같습니다.
해당 앱의 서버 IP 설정이 127.0.0.1 로 되어 있는데, 해당 설정을 서버 IP(source IP)로 변경하거나 해당 값을 제거하면 정상적으로 동작할 것 같습니다.
response 200 코드만 오고 실질적인 access_token 은 조회되지않습니다.
데이터를 가져오는 부분에 문제가 있는지요 ?..
POST /oauth/token 요청에 대헛 200을 리턴받았다면 json 포맷의 데이터에 access_token 데이터가 응답되도록 되어 있습니다.
본 글에서 공유해주신 앱키(client_id 파라미터)로 요청된 로그를 확인해보니 모두 IP 검증 에러가 응답된 것으로 확인됩니다.
정확한 요청 정보를 알려주시면 원인 파악에 도움이 될 수 있을 것 같아요~
사용자 정보 들고오기 카카오 테스트 예제를 참고하여 다시 요청했더니 이렇게 나옵니다.
위 답변처럼 server.xml 에서 수정하여 IP를 부여했습니다.
IP 검증 문제라면 어디를 수정해야하는지요 ??

앱이름이 “정부입법” 이 맞나요?
그렇다면 해당 앱 설정 중 “허용 서버 IP 주소” 정보에 테스트하고 계신 서버의 공인 IP(source ip) 주소로 변경하시면 문제가 해결 될 것 같습니다.
