Target must exist

Error

Target must exist

What it means

Puppeteer raised this from its Puppeteer runtime 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("Target must exist")) {
    // Apply the fix above, then retry or fail with a clearer message.
  }
  throw error;
}
