Why am I getting \"WebDriverException: Invalid Argument\" with GeckoDriver on my Raspberry Pi 3?

WebDriverException: Invalid Argument Error in Selenium with GeckoDriver on Raspberry Pi 3

This exception occurs when you attempt to interact with a WebDriver instance that has previously been terminated. The question relates to a scenario where Selenium is used with Firefox on a Raspberry Pi 3 device, encountering the error:

selenium.common.exceptions.WebDriverException: Message: invalid argument: can't kill an exited process

To address this issue, ensure that you are running Firefox in headless mode if your system does not have a display:

<code class="python">options = Options()
options.headless = True
driver = webdriver.Firefox(options=options)</code>

Additionally, verify that you are using compatible versions of Firefox, Selenium, and Geckodriver. Consult the Mozilla documentation for the specific compatibility requirements:
