木偶：如何处理窗户关闭？

Question

如果单击它，我有一个按钮，它会打开一个新窗口，并且我可以访问其DOM，但是当我关闭它并想访问我的上一页做某些事情时，我会出错

Error: Node is detached from document
    at ElementHandle._scrollIntoViewIfNeeded (C:\Users\user\Desktop\doc\node_modules\puppeteer\lib\ElementHandle.js:75:13)
    at <anonymous>
    at process._tickCallback (internal/process/next_tick.js:188:7)

我的代码如下

    const newPagePromise = new Promise(x => browser.once('targetcreated', target => x(target.page())));
    await linkhandle[i].click();
    const popup = await newPagePromise;
    // some DOM hocus focus with popup DOM
    popup.close();

// some DOM hocus focus with primary page which opened the popup
