in your conf.js file change to chromeOnly: false

exports.config = {
  allScriptsTimeout: 11000,

  specs: [
    'e2e/*.js'
  ],

  capabilities: {
    'browserName': 'chrome'
  },

  framework: 'jasmine',

  jasmineNodeOpts: {
    defaultTimeoutInterval: 30000

Answer 2

For those who are on a Mac and getting this error, the following open issue can cause this: https://github.com/angular/webdriver-manager/issues/476

The solution is provided by ciekawy. In

node_modules/webdriver-manager/built/lib/files/file_manager.js or

node_modules/protractor/webdriver-manager/built/lib/files/file_manager.js

add the following code at line 166:

fileUrl.url = fileUrl.url.replace(/_m1/, '');

You will then need to update the chrome drivers to pick up the change. If using NRWL's NX monorepo management tools:

npx webdriver-manager clean
npx webdriver-manager update --gecko=false --versions.chrome=<version from chrome://versions>
