When working with the versatile Selenium framework for web automation in combination with Node.js, you might encounter an error message: "until is not defined". This error often crops up when trying to implement wait conditions in your scripts. But fret not! With a few adjustments, you can resolve this issue and ensure your elements scroll into view properly.
