Not getting reponse back directly from filter

[AniS-03]

Serverless Java Container version: 2.0.0

Implementations: Spring Boot 3

Framework version: SpringBoot 3.3.0-SNAPSHOT

Frontend service: HTTP API

Deployment method: SAM

Scenario

I was trying to send response back directly from filter itself for certain condition.

Expected behavior

Was expecting that I will get the response which is provided in code.

Actual behavior

Getting 502 BAD GATEWAY as function got timed out.

Steps to reproduce

It can be reproduce by running this demo application using docker or on linux architecture as a native web app using sam-cli. This demo app build upon base project pet-store-native. Filter created

@Component
public class OutsideSecurityFilter extends OncePerRequestFilter{

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
            throws ServletException, IOException {

        System.out.println("Outside security filter chain.");

        if("OPTIONS".equals(request.getMethod())) {

            System.out.println("Inside OPTIONS call");

            response.addHeader("Name", "Aniket Saini");
            response.setStatus(200);
            return;
        } else {
            filterChain.doFilter(request, response);
        }
    }
}

To check just make a OPTIONS call on /hello. Or just run following command curl --request OPTIONS http://127.0.0.1:3000/hello
