[🐛 Bug]: selenium.common.exceptions.InvalidSessionIdException: Message: invalid session id

[kingrapha]

What happened?

Python language bindings for selenium WebDriver raises a selenium.common.exceptions.InvalidSessionIdException: Message: invalid session id. The browser is closed without triggering driver.quit() or driver.close() yet.

This on selenium grid 4.9.1 configured in kubernetes cluster using helm chart selenium-grid-0.18.0 with keda auto scaling. In values.yaml file: ChromeNode: extraEnvironmentVariables:

• name: SE_NODE_SESSION_TIMEOUT value: “900”

  terminationGracePeriodSeconds: 30 lifecycle: {} preStop: exec: command:

  • bash
  • -c
  • | curl -X POST 127.0.0.1:5555/se/grid/node/drain --header 'X-REGISTRATION-SECRET;' && \ while curl 127.0.0.1:5555/status; do sleep 1; done

How can we reproduce the issue?

options = Options()
options.add_argument(—-no-sandox’)
options.add_argument(—-disable-infoxbars’)
options.add_argument(—-disable-hang-monitor’)
options.add_argument(—-disable-setuid-sandbox’)
options.add_argument(—-disable-dev-shm-usage’)

caps = {‘browserName’: ‘chrome’, ‘platformName’: ‘LINUX’, ‘acceptInsecureCerts’: True}

driver = webdriver.remote(command_executor= https://selenium-grid-url, desired_capabilities=caps, options= options)
try:
   driver.get(“testing application url”)
   wait = WebDriverWait(driver, 60)
   element = wait.until(EC.element_to_be_clickable((By.ID,”locator”)
   element.click()
   wait.until(EC.invisibility_of_element_located((By.ID, “loading-bar”)
   ………more test code……
finally:
   driver.quit()

This has been several times reported and most of the time is the lack of configuration, please read https://www.selenium.dev/blog/2022/scaling-grid-with-keda/ and check your settings. We are merging a PR with Keda integration soon so this should be more straightforward.
