jestjs - 运行 jest-puppeteer 测试时未处理的错误

Question

我正在尝试为我的 puppeteer 操纵者项目设置测试。我按照基本指南进行操作并且测试通过，但终端中出现 2 个控制台错误。

使用 https://google.com 时没有出现错误或 https://youtube.com 。所以它看起来可能与特定站点有关？

 console.error

这是我的代码

describe('NCAA Home', () => {
    beforeAll(async () => {
      await page.goto('http://stats.ncaa.org/rankings/change_sport_year_div');
    });
  
    it('should be titled "NCAA Statistics"', async () => {
      await expect(page.title()).resolves.toMatch('NCAA Statistics');
    });
});

这是我的 jest.config.js

module.exports = {
    preset: "jest-puppeteer",
    testMatch: [
      "**/test/**/*.test.js"
    ],
    verbose: true
}

包.json

{
  "name": "stackoverflow",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "jest": {
    "preset": "jest-puppeteer"
  },
  "scripts": {
    "test": "jest"

    "jest-puppeteer": "^4.4.0"
  },
  "dependencies": {
    "puppeteer": "^5.1.0"
  }
}

我遇到的所有事情都提到了 async/await 的问题，但我尝试过的任何事情都会产生相同的错误，如果不是，还会产生更多的错误。我用这些文件创建了一个新项目，但我遇到了同样的错误

错误来自网站本身。检查网站的控制台。因此，对于像 google.com 或 youtube.com 这样的网站，它可以正常运行。
