Upgrade to vaadin 23.2 causes navigation to fail/timeout
Description of the bug
We have just upgraded from vadin 23.1.3 to 23.2.0
We have an oauth login process that displays a 'validating login' page which is displayed whilst a background thread completes the validation. Once the validation completes we essentially call:
ui.access(() -> UI.getCurrent().navigate(HomePage.class);
The problem is that the navigation is hanging for some 10+seconds and then continues. In the browser console logs we are seeing: Firefox can’t establish a connection to the server at wss://squarephone.biz:45801/VAADIN/.
Watching the network traffic it looks like that after the second time firefox complains (with the above error), vite then does a restart and then the login resumes.
This is in a development environment so I assume that vite is running its own little server.
We have had this same problem with earlier attempts to move to vaadin/vite.
If I re-activate webpack via: com.vaadin.experimental.webpackForFrontendBuild=true
Then the problem goes away.
Expected behavior
navigation to home page should proceed without a long delay.
Minimal reproducible example
as per the bug description.
Versions
- Vaadin / Flow version: 23.2
- Java version: 17
- OS version: ubuntu 22.04
- Browser version (if applicable): firefox 104.02
- Application Server (if applicable): spring boot
- IDE (if applicable): eclipse
I've just tested using vite with chrome and chrome doesn't have the same problem.
So this looks like its a vite/firefox bug.
Hi, are you able to create a small example project that demonstrates the problem? Without any possibility to debug it sounds quite impossible to fix. If oauth2 is relevant, maybe it can be based on the test project in https://github.com/vaadin/flow/issues/14253#issuecomment-1212577437, otherwise maybe based on start.vaadin.com

@bsutton Closed, because of no answer since Sep 15. Please provide a reproducible example project and re-open this ticket if it still an issue for you.
