flow: java.lang.UnsupportedOperationException: Unexpected message id from the client

Description of the bug

From time to time I may see the following PUSH error in the logs:

Expected behavior

Theres is no such issues in the Vaadin application

Minimal reproducible example

n/a. I see such issue on the prod env. from time to time

Thanks, I mean I’d like to intercept this on the client in order to reload the page from JS call.

PROD env: few times per day I face this situation on my iPhone (Safari browser), typically after sleep mode and moving between Wi-Fi and LTE connections. And some times on my Win10 PC with FF browser also after sleep mode.

DEV env: today 1 time I faced it during application restart on my local env: Win10 + FF browser

sure,

I applied your fix with r.close() Removed PWA annotation.

Linux:

sysctl -w net.ipv4.tcp_retries2=5
sysctl -w net.ipv4.tcp_keepalive_time=120
sysctl -w net.ipv4.tcp_keepalive_intvl=1
sysctl -w net.ipv4.tcp_keepalive_probes=5

NGINX

proxy_buffering         off;
keepalive_timeout       75s;
client_body_timeout     70s;
client_header_timeout   70s;

proxy_connect_timeout   10;
proxy_read_timeout      70;
proxy_send_timeout      70;

Tomcat/Spring Boot

server.servlet.session.persistent=false
server.servlet.session.timeout=30m
server.servlet.session.tracking-modes=cookie
server.servlet.session.cookie.http-only=true
server.servlet.session.cookie.secure=true
server.servlet.session.cookie.max-age=365d

server.tomcat.connection-timeout=70000
server.tomcat.keep-alive-timeout=75000

Vaadin

vaadin.heartbeatInterval=30
vaadin.pushLongPollingSuspendTimeout=60000
vaadin.maxMessageSuspendTimeout=5000
vaadin.closeIdleSessions=false
vaadin.eagerServerLoad=false

I still experience occasional issues with the PUSH feature not working on my iPhone, but it occurs less frequently than before.

@mcollovati most recent update:

  1. I applied your original fix (without r.close()).
  2. I played with NGINX settings, optimized timeouts, etc. But the most crucial thing in NGINX config (I suspect) is that I changed tcp_nopush to off. I found this recommendation here https://serverfault.com/questions/643348/how-to-flush-nginxs-ssl-buffer-mid-request-for-server-push. Also I found some comments:
tcp_nopush on; # off may be better for *some* Comet/long-poll stuff
tcp_nodelay off; # on may be better for some Comet/long-poll stuff

source: https://gist.github.com/bimbiero/3100422

Now, the application has been stable on my iPhone for several hours at least. Thank you again! I will continue monitoring it.

A quick update on this ticket

I did some further tests, and it seems atmosphere-js is working appropriately and not loosing messages on reconnect.

However, I noticed that sometimes on reconnect, a message is pushed, but the response seems not to be flushed, so the client receives it only after the polling timeout expires. When this happens, the Flow client is waiting for a missing message, and since it does not receive it in 5 seconds, it forces the full resynchronization.

Unfortunately, the cause for the response not being immediately flushed is not clear at the moment.

Also, I’m unable to open the mentioned GitHub issue. Is it in a private repository?

No, I simply pasted a wrong URL 😃 It is fixed now

As said, #16660 should fix part of the problem. For eagerServerLoad further investigation is required

After a brief look, it seems that #16660 may fix part of the issue. But I can still see resynchronization requests when the eagerServerLoad feature is activated.

That’s crazy, but I’m unable to reproduce issue #1 on localhost. However, this issue is reproducible on the production environment where NGINX is involved. So, I suspect right now that there is some NGINX misconfiguration or something like that.

Sure, let me see what I can do with a sample project. The biggest problem that this project is a huge code base… I’ll try

I think this is because I redeployed the app on prod… Enabled Vaadin and Atmosphere logs:

logging.level.com.vaadin=DEBUG logging.level.org.atmosphere = DEBUG

I checked all of the code, there are no such issues. I always use the following pattern:

        var ui = UI.getCurrent();
        listenableFuture.addCallback(jobApplicationMatrix -> {
            ui.access(() -> {
                //do some ui updates
                ui.push();
            });
        }, err -> {
            logger.error("Error", err);
            ui.access(() -> {
                //do some ui updates
                ui.push();;
            });
        });
