How to fix the Puppeteer error: Requesting main frame too early!
Error
Requesting main frame too early!
What it means
Puppeteer raised this from its frame and evaluation 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
- Check the API call that produced the error and validate its options before passing them to Puppeteer.
- Reduce the script to the smallest failing action, then add waits or state checks around that action.
- Keep Puppeteer and the browser revision aligned, especially in CI caches and Docker images.
Minimal guard
try {
// Run the Puppeteer operation that triggers this error.
} catch (error) {
if (error instanceof Error && error.message.includes("Requesting main frame too early!")) {
// Apply the fix above, then retry or fail with a clearer message.
}
throw error;
