REST API로 로그인 설정 시 remember-me 문제

안녕하세요, 기선님. 항상 강좌 잘 듣고 있습니다! 다름이 아니라, 제가 이 강좌를 바탕으로 현재 프로젝트를 진행중인데 프론트엔드는 Vue.js로 진행하므로 rest api를 사용하고 있습니다. 현재 postman으로도 테스트중인데 alwaysRemember 값을 true로 설정해도 remember-me 쿠키가 들어오지 않더라구요 ㅜㅜ 하지만 네이버 oauth2 로그인을 하면 또 멀쩡하게 들어옵니다.. 현재 일반 로그인에서는 리다이렉션을 막아뒀는데 혹시 그것과 관련이 있을까요? 며칠동안 이것저것 찾아보다 도저히 답이 안나와서 이렇게 질문 남깁니다..

코드도 첨부하겠습니다

@Component
public class AuthSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {
    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws ServletException, IOException {
        response.setStatus(HttpServletResponse.SC_OK);
    }

}

@Slf4j
public class CustomAuthenticationFilter extends UsernamePasswordAuthenticationFilter {

    private boolean postOnly = true;
    private HashMap<String, String> jsonRequest;

    @Override
    protected String obtainPassword(HttpServletRequest request) {
        String passwordParameter = super.getPasswordParameter();
        if(request.getHeader("Content-Type").equals(ContentType.APPLICATION_JSON.getMimeType())) {
            return jsonRequest.get(passwordParameter);
        }
        return request.getParameter(passwordParameter);
    }

    @Override
    protected String obtainUsername(HttpServletRequest request) {
        String usernameParameter = super.getUsernameParameter();
        if(request.getHeader("Content-Type").equals(ContentType.APPLICATION_JSON.getMimeType())) {
            return jsonRequest.get(usernameParameter);
