문의 시, 사용하시는 개발환경과 디벨로퍼스 앱ID를 알려주세요.

jsp, spring 레거시 프로젝트에서 사용. 기존에 다른 카카오 restAPI 연동시에는 로그인이 되는데 새로 계정을 변경하니까 안되네요 앱 ID 101776 입니다.

에러 Response Body를 조회 하시면 자세한 에러 메시지지를 확인 하실 수 있습니다.
액세스 토큰과 인가코드가 유효하지 않아 에러 발생한 것으로 추정되는데요.
디벨로퍼스앱을 식별할 수 있는 파라메터를 잘못 설정한 경우 101776 디벨로퍼스앱이 특정안되어 로그 조회 할 수 없습니다.

(1) 에러 응답 메시지 확인 부탁드려요.

(2) 액세스 토큰 발급에 사용하신 인가코드 기재해주시면 로그 확인해보겠습니다.

에러 Trace 가 아니라 Response Error Body 확인 해보셔야한다는 의미였는데요.
Java 에서 HttpURLConnection 객체 사용하는 경우 아래와 같이 확인 할 수 있습니다.

			InputStream stream = conn.getErrorStream();
		    if (stream != null) {
			    try (Scanner scanner = new Scanner(stream)) {
			        scanner.useDelimiter("\\Z");
			        response = scanner.next();
			    }			
			    System.out.println("error response : " + response);
		    }

해당 인가코드는 101776 앱에서 발급받은게 아니라
센택(1017766) 디벨로퍼스앱에서 발급받은 코드입니다.

(1) JS SDK에서 init하는 앱키는 JAVASCRIPT_KEY를 사용해주세요.

(2) 기재하신 인가코드로 센택(1017766) 디벨로퍼스앱의 앱키이용하여 /oauth/token 액세스 토큰 발급 요청 시, 전달된 에러는 아래와 같습니다.

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

조금전 클라이언트 시크릿 비활성화 하셔서 현재는 오류 발생하지 않을 것으로 보입니다.
