I am trying to capture the backend data from the network tab of chrome dev tools using the selenium protractor framework but unable to get a perfect code. I have tried the below code to capture the data but getting error.

capabilities: {
    'browserName': 'chrome',
    'chromeOptions': {
      'perfLoggingPrefs': {
        'enableNetwork': true,
        'enablePage': false,
        'enableTimeline': false
      }
    },
    loggingPrefs: {
      performance: 'ALL',
      browser: 'ALL'
    }
  },



 afterEach(() => {
    browser.manage().logs().get('performance').then((browserLogs) => {
      browserLogs.forEach((browserLog) => {
        var message = JSON.parse(browserLog.message).message;
        if (message.method == 'Network.responseReceived') {
          console.log(message);
        }
      });
    });
  });
