google-chrome - 调用 AWS Lambda 容器映像时进程退出并显示错误代码 100

Question

我正在关注https://docs.aws.amazon.com/lambda/latest/dg/images-create.html并从 AWS 基础映像为 Lambda 创建了一个映像，并在将其推送到 ECR 之前先在本地对其进行了测试。在本地调用函数时，我得到了预期的结果，即错误代码 0。但是在 ECR 上推送图像并从 AWS lambda 控制台调用它之后，我得到了以下问题。

  npm.load(function() {
    var child = childProcess
    .fork(path.join(npm.root, 'protractor/bin/protractor'), args)   
        .on('close', function(errorCode) {
      console.log('error code: ', errorCode);

      // Use this block to have Lambda respond when the tests are done.
      const response = {
        statusCode: 200,
        body: JSON.stringify({
          message: `Selenium Test executed on Chrome ! Child process Error Code: ${errorCode}`,
        }),
      };
      callback(null, response);
    });
    process.on('SIGINT', child.kill);
  });


};

index.js

const {by} = require("protractor");
const {protractor} = require("protractor");
const {browser} = require("protractor");
describe('Google\'s Search Functionality', function() {
    it('can find search results', async function() {
        const signin = "Sign in"
        await browser.waitForAngularEnabled(false);
        await browser.get('https://google.com/ncr');
        await browser.findElement(by.name('q')).sendKeys('BrowserStack', protractor.Key.ENTER);
        const texti = browser.findElement(by.xpath('//a[contains(@href,"sign_in")]'));
        expect(await texti.getText()).toEqual(signin);
    });
});

所有这些文件都在根项目目录中的同一级别。

我用谷歌搜索了很多，但找不到合适的分辨率。是权限问题吗？因为我不明白是什么让相同的 lambda 容器映像在 lambda 控制台中失败，而不是在本地失败。
