selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status 1 running Selenium Chrome Driver inside Python project

Question

I am running the following code:

from selenium import webdriver

driver = webdriver.Firefox()  
driver.get("https://web.whatsapp.com/")

I have installed firefox under /usr/bin/firefox and geckodriver (same version) under /usr/bin/geckodriver

However, I am getting the following stacktrace error when the Python code is run:

selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status 1

How are you getting _`['"917570090256"', '"Hello world"', '"sidhwa JIIT"', '"temp"']`_ — undetected Selenium, Mar 26 '22 at 17:53
it's a part of the script I am running, however the stack trace error occurs as the reason of some problem with selenium driver — nvster, Mar 26 '22 at 18:29

This error message...

selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status 1

...implies that the GeckoDriver was unable to initiate/spawn a new Browsing Context i.e. firefox session.

Possibly there are some incompatibility between the version of the binaries you are using.

I have the same error message when I running Selenium 4 + Firefox on Centos 8

I check the log file geckodriver.log

It is showing

Running Firefox as root in a regular user's session is not supported.

so I'm using a non-root user to run the same Python script, It is working now.
