protractor + angular 6 library throw Error: ReferenceError: window is not defined

Question

may I ask you why my app works with ng serve and ng build but if I run protractor, my e2e test fails with this message?

[16:35:07] I/launcher - Running 1 instances of WebDriver
[16:35:07] I/direct - Using ChromeDriver directly...
[16:35:13] E/launcher - Error: ReferenceError: window is not defined

Following the tsconfig.e2e

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/e2e",
    "module": "commonjs",
    "target": "es2017",
    "types": [
      "jasmine",
      "node"
    ]
  }
}

And this is my tsconfig.app

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "module": "es2015",
    "baseUrl": "",
    "types": [
      "node"
    ]
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ]
}
