What does the 'DeprecationWarning: The URL is invalid. Future versions of Node.js will throw an error' message signify?

This warning indicates that you are using a method or pattern for URL handling in Node.js that is no longer supported or will be removed in future versions. Specifically, it's related to how URLs were parsed or constructed, and the current approach will soon be replaced by stricter error handling, leading to a thrown error instead of just a warning.
