[SpringCloudGateway]: Post filters are not executed after endpoint redirection timeout about spring-cloud-gateway HOT 5 OPEN

@shashikanth8639 Post filter is implemented in following way:

@Override
public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
    return chain.filter(exchange).then(Mono.fromRunnable(() -> {
        final ResponseCookie  resCookie = ResponseCookie.from(this.cookieName, "invalidated").httpOnly(true).secure(true).path("/").maxAge(0).build();
        exchange.getResponse().addCookie(resCookie);
   }));
}

This post filter executes for 404 and 503 response status from endpoint, however fails to execute when API gateway times-out the endpoint call (endpoint take more than 30sec to respond).

@deepak-chhetri have you tried using the onError method?

Thanks @shashikanth8639 for sharing the pointer. Do you mean Mono.onError()(publisher) method?

However I need to figure out why post filters are not executing when endpoint call gets timeout so that better error handling mechanism can be implemented. Since for other 4xx and 5xx status code, post filters are getting executed.

400 and 500 errors are responses from the server. A timeout is a local exception. Have you tried #3264 (comment)
