木偶人无法使用evaluate获取页面的innerHTML

const puppeteer = require('puppeteer');

async function getInnerHTML(url, selector) {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto(url);
  await page.waitForSelector(selector);
  const innerHTML = await page.evaluate((sel) => {
    const element = document.querySelector(sel);
    return element ? element.innerHTML : null;
  }, selector);
  await browser.close();
  return innerHTML;
}

const url = 'https://example.com';
const selector = '#target-element';
getInnerHTML(url, selector)
  .then((innerHTML) => {
    console.log(innerHTML);
  })
  .catch((error) => {
    console.error(error);
  });
