WebDriverException: Message: Service chromedriver unexpectedly exited. Status code was: 127

This error occurs when the Selenium WebDriver service fails to start properly, typically due to missing dependencies. When the error message indicates "excited" rather than "exited," it's likely a typo in the error report.

Potential Causes and Resolution

The underlying cause of this issue is usually a missing library or dependency that is required for the WebDriver service to function. To resolve this issue, you can try the following steps:

1. Install Missing Dependencies: Use the apt-get command to install the missing libraries. The specific libraries required may vary depending on your operating system and the version of WebDriver you are using. In the example provided, the following command resolved the issue:

apt-get install -y libglib2.0-0=2.50.3-2 \
libnss3=2:3.26.2-1.1+deb9u1 \
libgconf-2-4=3.2.6-4+b1 \
libfontconfig1=2.11.0-6.7+b1

2. Identify Missing Dependencies: To identify which dependencies are missing, you can use the ldd command to print the shared object dependencies of the WebDriver executable. Compare the output with the list of required dependencies and install any missing libraries accordingly.

Additional Tips

• If you are using Docker to run your code, make sure you have installed the necessary libraries within the container.
• If you have a headless environment (without a GUI), you may need to install additional dependencies such as Xvfb (X virtual frame buffer).
• Keep your WebDriver and browser versions up to date to minimize the risk of compatibility issues.

By following these steps, you should be able to resolve the "WebDriverException: Service chromedriver unexpectedly exited" error and get your Selenium WebDriver service running smoothly.
