[🐛 Bug]: Python - staleness_of is crashing with Node with given id does not belong to the document

[nijel]

What happened?

The staleness_of predicate occasionally crashes with:

selenium.common.exceptions.WebDriverException: Message: unknown error: unhandled inspector error: {"code":-32000,"message":"Node with given id does not belong to the document"}

This happens like in a few percent of test runs. Maybe this error should consider the element to be stale as well?

How can we reproduce the issue?

old_page = driver.find_element(By.TAG_NAME, "html")
button = driver.find_element(By.ID, "login-button")
button.click()
WebDriverWait(driver, timeout).until(staleness_of(old_page))

@nijel can you provide a full reproducible code along with the url to reproduce this issue independently? It will help in triaging

As mentioned before, it isn't reliably reproducible, it happens occasionally. To me, it looks like it needs to hit a certain time when the browser is in the middle of loading the next page and the selected element is still available (“Node with given id does not belong to the document”), but is not yet stale to trigger StaleElementReferenceException.

The snippet is from our test suite, in this particular case it is testing the login page which does nothing complex (a form where submit button is clicked). It can be seen online, for example, at https://hosted.weblate.org/accounts/login/.

I've now got the failure with selenium logging enabled, posted the logs above, the full job is here: https://github.com/WeblateOrg/weblate/actions/runs/13806523670/job/38618335307

If you have any idea how to debug this deeper, I'm happy to include that in our CI.

I don't think I've seen this issue before upgrading Selenium to 4.29.0 (from 4.28.1), but it might be just a coincidence (it might also be that the Chrome and/or ChromeDriver were updated inside the GitHub Actions meanwhile).

[nijel]

https://issues.chromium.org/issues/375343406 might be related (but doesn't give much info).

[javierm]

We're getting the same error in GitHub Actions quite often since two days ago. Happens with both Selenium 4.25.0 and 4.29.1. We're using Ruby with Capybara, though. My best guess is that it's related to a change in GitHub Actions and they're now using a different version of Chromium 🤔. Or maybe they changed something that made the tests slower and that somehow affects the results.

Here's an example of a test run that failed a few times with Selenium 4.25.0 and another example with Selenium 4.29.1.

We haven't been able to reproduce any of the failures, though, with each test run failing on different tests.

[nijel]

Looking back at the workflow logs, I can't locate such an issue with Chromium 133.0.6943.0 / ChromeDriver 133.0.6943.141 which were used before. With Chromium 134.0.6998.0 / ChromeDriver 134.0.6998.35 there is quite likely that the test will fail.

WeblateOrg/weblate#14187 seems to be a workaround for us.
