Not able to run my test cases on protractor 2.5.1

Question

my conf.js:

exports.config = {
  seleniumAddress: 'http://localhost:4444/wd/hub',
  capabilities: {
    'browserName': 'firefox'
  },

  onPrepare: function() {
      browser.driver.manage().window().maximize();
      protractor.basePath = __dirname;

  },
  suites : {
  qa:   ['./specs/log_in.js','./specs/create_project_external_roles.js','./specs/create_position_us_roles.js',

 beta:   ['./specs/log_in_beta.js','./specs/create_position.js', './specs/candidate_status.js'],

  },

  jasmineNodeOpts: {
      defaultTimeoutInterval: 3000000,
      allScriptsTimeout: 3000000,
      rootElement: "div",
      showColors: true
  },
  baseUrl: '',
};

Until last Friday evening, this worked fine. Suddenly, I am getting this error:

Failed: Error while waiting for Protractor to sync with the page: "angular could not be found on the window".

Answer 1

As pointed out by @raghavendra, rootElement has be specified on the top level of your config:

exports.config = {
    rootElement: "div"
},

Answer 2

@raghavendra t, as showed in your html, you must set your rootElement like this:

rootElement: '.ng-scope', 

So, your config file would be like this:

exports.config = {
  seleniumAddress: 'http://localhost:4444/wd/hub',
  capabilities: {
    'browserName': 'firefox'
  },

  onPrepare: function() {
      browser.driver.manage().window().maximize();
      protractor.basePath = __dirname;

  },

      allScriptsTimeout: 3000000,
