Error parsing HTTP request header 에러

안녕하세요 v5 추가하고 나니 갑자기 이전 작업들도 안되고 다음 오류가 떠서 질문 남깁니다ㅠㅠ

서블릿, JSP, 서블릿 MVC 중에서 서블릿만 작동되고 JSP는 누르면 파일이 다운로드 되네요

나머지는 Whitelabel Error Page와 404가 뜹니다

뭘 잘못 건드린건지 감도 안잡혀요

검색해보니 인코딩 문제일수도 있다는데 저는 크롬을 사용해서 자동으로 인코딩 될텐데.. 문제를 모르겠어요 ㅠㅠ

제 코드는 아래와 같습니다

오류나는 구간은 branch 따로 분리해두었습니다
