Selenium.common.exceptions.webdriverexception: Message: Invalid Argument: Value Must Be A Non-negative Integer With Chromedriver And Selenium

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.clos

Solution 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.
