Understanding the Error The error occurs when the WebDriver attempts to interact with an element that isn't present in the DOM at the time the command is executed. Factors contributing to this could include: Element still loading: The element may not have loaded fully before your script attempts to interact with it. Incorrect selector: The CSS selector or other identifier for the element may be wrong. The example issue comes from a script trying to find a user profile link after logging into GitHub but can't due to timing or selector problems. Steps to Resolve the Error 1. Print the Page Source One immediate way to diagnose the problem is by printing out the HTML of the page when you encounter the error. You can do this using: [[See Video to Reveal this Text or Code Snippet]] This will help you ensure the element you are trying to select is indeed present on the page. 2. Implement a Wait To ensure that elements are fully loaded before you interact with them, use waits. There are two methods you can employ: Option A: Use time.sleep() This method is straightforward but not the most efficient. You can add a pause in your script: [[See Video to Reveal this Text or Code Snippet]] This deliberately halts your script for a set number of seconds, giving the page time to load. However, it can increase the overall execution time of your script. Option B: Use WebDriverWait For a more advanced solution, use WebDriverWait, which allows you to wait until a specific condition is met before proceeding. Here’s how you can implement it in your script: [[See Video to Reveal this Text or Code Snippet]] 3.
