Error in localized configuration

Hello All , I am trying to follow the given documentation to implement sso based on docs .

For the testing , i just hardcoded to some dummy user id and groups and trying to access the camunda webapp , I could see empty page is displayed [without cokcpit/admin/tasklist] and the roles for the same users were not displayed underneath his name .

The Code sample :

This is my Spring security auth provider .

    public AuthenticationResult extractAuthenticatedUser(HttpServletRequest request, ProcessEngine engine) {
        System.out.println("Enter SpringSecurityAuthProvider >>> ");
        final HttpServletRequest req = (HttpServletRequest) request;
         AuthenticationResult authenticationResult = new AuthenticationResult("Test.User@xyz.com", true);
        authenticationResult.setGroups(ImmutableList.of("TESTING_GROUP_A","TESTING_GROUP_B"));
        System.out.println("getGroups :=>" + authenticationResult.getGroups());

        System.out.println("Exit SpringSecurityAuthProvider <<< ");
        return authenticationResult;
    }

Below is my stateless Auth filter :

public class StatelessAuthenticationFilter implements Filter {

    private static final Logger LOG = LoggerFactory.getLogger(StatelessAuthenticationFilter.class);


    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        System.out.println("Enter StatelessAuthenticationFilter >>> ");
        ProcessEngine engine = EngineUtil.lookupProcessEngine("default");
        final HttpServletRequest req = (HttpServletRequest) request;
        SSPGoAuthenticationToken principal = (SSPGoAuthenticationToken) req.getUserPrincipal();
        String name = principal.getName();
        try {
            Authentications authentications = Authentications.getFromSession(req.getSession());
            engine.getIdentityService().setAuthentication("Test.User@xyz.com", ImmutableList.of("TESTING_GROUP_A","TESTING_GROUP_B"));
           
            System.out.println("Delegating to Chain#doFilter");
            chain.doFilter(request, response);
        } finally {
            engine.getIdentityService().clearAuthentication();
        }


    }

How to get this corrected ?

I do have the localization error when deployed into openshift platform
