Tab target session is not defined.

Error

Tab target session is not defined.

What it means

Puppeteer raised this from its page operations code. In practice, it usually means your script reached a browser, page, frame, element, or option state that the API cannot use safely.

How to fix it

• Make sure the page, browser context, and CDP session are still open before issuing the command.
• Avoid racing cleanup code with pending Puppeteer operations; await the operation before closing the page or browser.

Minimal guard

try {
  // Run the Puppeteer operation that triggers this error.
} catch (error) {
  if (error instanceof Error && error.message.includes("Tab target session is not defined.")) {
    // Apply the fix above, then retry or fail with a clearer message.
  }
  throw error;
