"readable is not async iterable" generating PDF with @cloudflare/puppeteer + Browser Rendering

Steps to reproduce the problem: Launch puppeteer and instantiate a Page with some content:

const browser = await puppeteer.launch(env.MYBROWSER);
const page = await browser.newPage();
await page.setContent('<h1>HELLO CLOUDFLARE</h1>', {
waitUntil: 'networkidle0',
});

Get the PDF: await page.pdf({ displayHeaderFooter: true }) Yields this error:
