Fix Puppeteer Navigation Failure

My Puppeteer script boots up just fine but stops dead once it begins its page-navigation sequence. No DOM is touched, no error is thrown to the console—execution simply halts and the browser instance hangs. I need a clean, well-commented patch that diagnoses and eliminates the issue so the script can navigate, interact, and exit normally every time.

Key context
• The problem presents “during execution,” never at start-up or shutdown.
• Failure point is the very first page.goto call inside an async function; everything after it is skipped.
• The script’s purpose is straightforward navigation across several internal URLs, with a few waits and selectors—no scraping or form submission.

What I need from you
1. Identify the root cause (timing, promises, unsupported flags, or anything else).
2. Modify the existing Node.js / Puppeteer code so navigation completes without hanging.
3. Add concise logging so I can trace future failures quickly.
4. Provide a short README section describing changes and any new npm flags or launch arguments required.

Acceptance criteria
• Running `node index.js` finishes the full navigation flow on my machine with the default headless setting.
• No unhandled promise rejections or silent timeouts longer than 10 s.
• All modifications remain compatible with the current Node LTS and the installed Puppeteer version.

Source code and a reproducible test URL will be supplied as soon as we agree to start.
