Question

I am working on selenium (3.5.0),Python 3.6.8 i wanted to test simple code that is written below

driver.implicitly_wait(10)
driver.get(url)
print(driver.title)
sleep(6)
driver.close()

but it is throwing an error i.e selenium.common.exceptions.WebDriverException: Message: invalid argument: value must be a non-negative integer I am not getting where i went wrong

I found similar issue raised by someone in this platform but my problem didn't get solved please help me in this regard

Answer 1

This error message...

selenium.common.exceptions.WebDriverException: Message: invalid argument: value must be a non-negative integer

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• Presumably you are using the latest chromedriver=77.0
• Presumably you are using chrome= 77.0.
• Your Selenium Client version is 3.6.8 which is ancient.

So there is a clear mismatch between the Selenium Client v3.6.8 , ChromeDriver v77.0 and the Chrome Browser v77.0

Solution

Ensure that:

• Selenium is upgraded to current levels Version 3.141.59.
• ChromeDriver is updated to current ChromeDriver v77.0 level.
• Chrome is updated to current Chrome Version 77.0 level. (as per ChromeDriver v77.0 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
• Take a System Reboot.
• Execute your @Test as non-root user.
• Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
