Puppeteer: The WebDriver BiDi implementation is failing to create a browsing context correctly.

BiDi context creation returned an ID before it was available in the context registry.

Error message

The WebDriver BiDi implementation is failing to create a browsing context correctly.

How this error happens

The BiDi browser returned a browsing-context ID before its corresponding context was registered. This is an internal initialization or registry check, not an application input validator.

Use a running WebDriver BiDi browser named browser. The following is a lifecycle race to rule out.

await Promise.all([
    browser.newPage(),
    browser.close(),
]);

Creation and shutdown overlap in this example. Depending on event order, Puppeteer may report a target/session-closed error instead. It is not a deterministic reproduction of this particular registry message.

How to fix

Keep the browser and context alive until creation and page work finish. Run the corrected sequence with a fresh live browser.

const page = await browser.newPage();

try {
    await page.setContent(
        "<p>Page task</p>"
    );
} finally {
    await page.close();
}

Things to keep in mind

If this exact initialization error persists with sequential public API calls, retain the full stack and a minimal reproduction and report the browser/Puppeteer failure. Do not manufacture target IDs, initialize private maps, or retry an external side effect blindly.
