| <h1>Fix: Puppeteer Timeout waiting for selector</h1> | |
| <div class="code-block">TimeoutError: waiting for selector `.product-price` failed: timeout 30000ms exceeded</div> | |
| <p>Are you banging your head against the wall because your Puppeteer scraper randomly broke? Here is why it happens, and how to fix it permanently.</p> | |
| </div> | |
| <section> | |
| <div class="section-label">The Problem</div> | |
| <h2 class="section-title">Why did my selector break?</h2> | |
| <div class="content-block"> | |
| <p>If you're getting a `TimeoutError` in Puppeteer or Playwright, it means the browser loaded the page, but the specific CSS class, ID, or XPath you asked for doesn't exist.</p> | |
| <p>This happens because modern websites use dynamic CSS frameworks (like Tailwind) or React. When the website deploys an update, their class names change automatically (e.g., from `.css-1b3x` to `.css-9x4y`).</p> | |
| </div> | |

| <div class="divider"></div> | |
| <section> | |
| <div class="section-label">The Fix</div> | |
| <h2 class="section-title">Stop using CSS Selectors</h2> | |
| <div class="content-block"> | |
| <p>You can spend 3 hours reverse-engineering the new DOM structure and pushing a hotfix to your scraper... but it will just break again next week.</p> | |
| <p>The permanent fix is to switch to <strong>OpticParse</strong>.</p> | |
| <ul class="feature-list"> | |
| <li>OpticParse doesn't use CSS selectors.</li> | |
| <li>It takes a screenshot of the webpage.</li> | |
| <li>It uses Vision AI to read the text exactly as a human sees it.</li> | |
| <li>It returns perfectly structured JSON.</li> | |
| </ul> | |
| <p>If a human can read the price on the screen, OpticParse will extract it—even if the underlying HTML completely changes.</p> | |
