"InvalidSessionIdException" while calling driver.quit()
Chandra Sekhar
Hi Community,
I used https://github.com/SeleniumHQ/docker-selenium helm charts to create the selenium grid in my GKE cluster but when I run the automation on that cluster, I could see “InvalidSessionIdException” very frequently while running.
I am using Python with pytest-selenium plugin for running the test cases.
The Majority of times I could see the issue when the test case failed and the pytest-selenium called driver.quit().
Does anyone has any idea?
request = <SubRequest 'driver' for <Function test_grid_find_REMOTE>>
driver_class = <class 'selenium.webdriver.remote.webdriver.WebDriver'>
driver_kwargs = {'command_executor': 'http://<IPAddress>/wd/hub', 'desired_capabilities': {'browserName': 'chrome', '...args': ['headless', '--window-size=1366,768', '--ignore-gpu-blocklist', '--disable-dev-shm-usage'], 'extensions': []}}}
@pytest.fixture
def driver(request, driver_class, driver_kwargs):
"""Returns a WebDriver instance based on options and capabilities"""
retries = int(request.config.getini("max_driver_init_attempts"))
for retry in Retrying(
stop=stop_after_attempt(retries), wait=wait_exponential(), reraise=True
):
with retry:
LOGGER.info(
f"Driver init, attempt {retry.retry_state.attempt_number}/{retries}"
)
driver = driver_class(**driver_kwargs)
event_listener = request.config.getoption("event_listener")
if event_listener is not None:
# Import the specified event listener and wrap the driver instance
mod_name, class_name = event_listener.rsplit(".", 1)
mod = __import__(mod_name, fromlist=[class_name])
event_listener = getattr(mod, class_name)
if not isinstance(driver, EventFiringWebDriver):
driver = EventFiringWebDriver(driver, event_listener())
request.node._driver = driver
yield driver
> driver.quit()

- Session Already Closed: If you have already closed the WebDriver session using driver.quit() earlier in your script, calling it again on the same driver instance will result in an InvalidSessionIdException. Ensure that you are not attempting to quit the session multiple times.
- Driver Instance Not Initialized: If you are trying to quit a driver instance that was not properly initialized or created, you may encounter this exception. Ensure that you have created and initialized the driver before calling driver.quit().
- Concurrent Sessions: If you are working with multiple WebDriver instances or managing WebDriver sessions concurrently, make sure you are calling driver.quit() on the correct driver instance. It's easy to mistakenly quit the wrong session if you have multiple drivers.
- Network Issues: In rare cases, network issues or communication problems between the script and the WebDriver server can lead to the session being invalidated. Ensure that your WebDriver server is running and accessible. Look out for the Grid Setting to keep the session time validity here.
