Why Am I Getting a 'NoSuchElementException' When Clicking a 'Next' Button with Selenium?

"NoSuchElementException" Error When Clicking "Next" Button with Selenium

The error message "selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element" indicates that the Selenium driver is unable to find the element you are attempting to click.

To resolve this issue, ensure that the element you are trying to click can be located with the provided locator strategy. In the case of the "Next" button, you can use either the css_selector or xpath locator:

# CSS selector
driver.find_element_by_css_selector("input[name='submitNext'][value='Next']").click()

# XPath
driver.find_element_by_xpath("//input[@name='submitNext' and @value='Next']").click()

Additionally, ensure that the versions of Selenium, ChromeDriver, and your browser are compatible. In the provided error message, it appears that there is a mismatch between ChromeDriver version 2.36 and Chrome version 66.0. Refer to the ChromeDriver release notes for compatible versions.

To resolve this, upgrade Selenium and ChromeDriver to the latest versions, clean your project workspace, and restart your system. Here are some optimization tips:

• Use the execute_script() method to execute JavaScript to click the button.
• Try to use a WebDriverWait to wait until the element is located.
• Ensure that the element is not hidden or disabled.
• Debug your code using breakpoints and print statements to ensure the correct element is being located.
