How to fix the Puppeteer error: Missing target on swap
Error
Missing target on swap
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("Missing target on swap")) {
// Apply the fix above, then retry or fail with a clearer message.
}
throw error;
