Puppeteer: Cannot extract value when objectId is given

An internal value-extraction path received an object reference where a by-value result was expected.

Error message

Cannot extract value when objectId is given

How this error happens

An internal primitive-value decoder expects a by-value result with no CDP object ID. A handle to an object instead has a reference ID.

The snippets use an open Chrome/CDP page named page. The correction continues with handle.

const handle = await page.evaluateHandle(() => {
    return {
        count: 3,
    };
});

const remote = handle.remoteObject();

console.log(remote.objectId);

How to fix

Use jsonValue or evaluation to extract serializable data from the handle through the public API.

try {
    const value = await handle.jsonValue();

    console.log(value);
} finally {
    await handle.dispose();
}

Things to keep in mind

The first snippet shows the reference-shaped input, not a direct invocation of the private primitive decoder. A correctly used public handle should route that input to the appropriate decoder automatically.
