getting page title: %w

Error message

getting page title: %w

What it means

Page.Title evaluates () => document.title in the main frame; this error wraps an evaluation failure, meaning the expression could not run: execution context destroyed by navigation, page closing, or renderer crash. The title value itself is irrelevant — the call to evaluate failed.

Solutions

1. Await a load state first: await page.waitForLoadState() before page.title()
2. Retry once after a short delay — a fresh execution context usually resolves it
3. Ensure the page is not closing when reading the title

Example fix

// before
await page.goto('https://example.com/');
const t = await page.title(); // may race redirect/context swap

// after
await page.goto('https://example.com/');
await page.waitForLoadState('domcontentloaded');
const t = await page.title();

if (page.isClosed()) throw new Error('page closed before title read');
await page.waitForLoadState('domcontentloaded');

let title;
for (let i = 0; i < 2; i++) {
  try { title = await page.title(); break; }
  catch (e) { if (!/getting page title/.test(e.message)) throw e; await page.waitForTimeout(200); }
}

When it happens

Trigger: page.title() during page.goto (context torn down and recreated), on an about:blank page being replaced, or after the page/renderer died.

Common situations: Calling page.title() immediately after goto without awaiting load; racing a redirect chain; calling at iteration teardown.
