I'm setting up CI for our project that is in Angular. We are using Google Cloud Platform's Cloud Builder for CI. Everything is going smoothly, we can setup the environment, install packages via npm, build the project using angular-cli and deploy. But the problem is that our test cases (e2e) in Protractor keeps getting an error. What are we missing here?

This is for the Continuous Integration using Google Cloud Builders, we are running the protractor in headless mode, and using the puppeteer's chromium as the chrome's binary path

This is my protractor.conf.js

// Protractor configuration file, see link for more information
// https://github.com/angular/protractor/blob/master/lib/config.ts

const { SpecReporter } = require('jasmine-spec-reporter');
const puppeteer = require('puppeteer');
process.env.CHROME_BIN = puppeteer.executablePath()

exports.config = {
  allScriptsTimeout: 1000000,
  specs: [
    './e2e/*.e2e-spec.ts',
    '../e2e/*.e2e-spec.ts'
  ],

  capabilities: {
    // browserName: 'chrome',
    browserName: 'chrome',
    chromeOptions: {
      binary: process.env.CHROME_BIN,
      args: ['--headless', '--disable-gpu', '--no-sandbox', '--disable-extensions', '--disable-dev-shm-usage', '--disable-setuid-sandbox']
    }
  },
  // seleniumAddress: 'http://127.0.0.1:4444/wd/hub',
  // ignoreUncaughtExceptions: true,
  directConnect: true,
  },
};

This is the error we are getting in cloud builders
