当出现“TimeoutError: waiting for Page.printToPDF failed”时，如何增加 pupetteer 的 Page.pdf 的超时时间？

Question

当尝试将大发票转换为 PDF 时，我收到“TimeoutError: waiting for Page.printToPDF failed”：

Unhandled Rejection at: Promise Promise { <rejected>
 TimeoutError: waiting for Page.printToPDF failed: timeout 30000ms exceeded

如何增加超时时间？

Answer 1

正如 Julien 提到的，将超时设置为 0。

const page = await browser.newPage();
await page.pdf({
    printBackground: true,
    displayHeaderFooter: false,
    timeout: 0,
});
