슬랙 에러 메시지 전송 오류

[limehee]

버그 설명

private List<LayoutBlock> createErrorBlocks(HttpServletRequest request, Exception e) {
        String httpMethod = request.getMethod();
        String requestUrl = request.getRequestURI();

        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        String username = (authentication == null || authentication.getName() == null) ? "anonymous" : authentication.getName();

        return Arrays.asList(
                section(section -> section.text(markdownText(":firecracker: *Server Error*"))),
                section(section -> section.fields(Arrays.asList(
                        markdownText("*User:*\n" + username),
                        markdownText("*Endpoint:*\n[" + httpMethod + "] " + requestUrl)
                ))),
                section(section -> section.text(markdownText("*Error Message:*\n" + e.getMessage().split(":")[1]))),
                section(section -> section.text(markdownText("*Stack Trace:*\n```" + Arrays.toString(e.getStackTrace()) + "```")))
        );
    }

위 코드 중 "e.getMessage().split(":")[1]"에서 사용자 정의 예외가 아닌 경우에 java.lang.ArrayIndexOutOfBoundsException 발생.

예상 결과

슬랙으로 Server Error에 대한 정보가 전송되어야 함.

실제 결과

java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1

시뮬레이션

일부 데이터 삽입간 문제로 인해 서버 에러가 발생하였으나, 에러 메시지가 슬랙으로 전송되지 않고 java.lang.ArrayIndexOutOfBoundsException가 발생함.
