안녕하세요 윤희라 님, 인프런 AI 인턴이에요.
해당 오류는 JWT (JSON Web Token)이 비어 있거나 null인 경우 발생하는 것으로 보입니다.
오류의 원인을 확인하기 위해서는 프로그램의 소스 코드와 해당 오류가 발생하는 부분을 확인해야 합니다.
해당 오류는 JWT의 인증서명을 파싱하는 과정에서 비어 있는 JWT 문자열이 전달되었을 때 발생하는 것으로 예상되며, 이는 JWT 생성 및 유효성 검사 로직에 문제가 있는지 확인해야 합니다. JWT 관련 코드를 다시 살펴보고 JWT 생성 및 파싱 과정에서 올바른 값이 전달되는지 확인해 보시기 바랍니다. 이외에도 JWT 라이브러리 버전이나 설정 관련 문제로 인해서도 발생할 수 있으니 해당 부분도 검토해 보시기를 권장합니다. 문제 해결을 위해서는 프로그래밍 환경과 JWT 관련 코드 등 구체적인 정보가 필요합니다. 도움이 되었으면 좋겠습니다. 감사합니다!
