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

This error occurs when trying to interact with a web browser using GeckoDriver, Selenium, and Python on a headless Raspberry Pi 3 system. The error message indicates that an attempt to terminate an exited process failed.

Root Cause

The primary issue here is that GeckoDriver is not properly configured for headless mode.

Solution

To resolve this problem, ensure that headless mode is enabled by making the following changes:

<code class="python">from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.headless = True  # Enable headless mode
driver = webdriver.Firefox(options=options)</code>

Compatibility Considerations

Additionally, verify that you're running compatible versions of Firefox, Selenium, and GeckoDriver. Refer to the official documentation for supported version combinations: https://firefox-source-docs.mozilla.org/testing/geckodriver/Support.html
