Received error message with npm run protractor config file which worked perfectly previously

I am creating my 1st protractor framework and I am trying run a sample test locally within my project. I can update and start webdriver fine. No issues at all. Super confused where I went wrong!

I got to project level and performed the command

npm run protractor

I got the following message from my mac terminal

Jacquelines-MacBook-Air:JSworkspace jacquelinegeorge$ cd LocatorTraining
Jacquelines-MacBook-Air:LocatorTraining jacquelinegeorge$ npm run protractor

So I checked the configurations.js file which looks like (that's the correct Spec.js file that I am testing):

exports.config = {
  seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['PageObjectLocator1.js'],
  capabilities: {
    browserName: 'chrome'
  },

  onPrepare: function() {
      browser.driver.manage().window().maximize(); 
     //logs
     //command for non angular web site

     //reporting
     //site Url???


  }
}

Then I went to the run configurations and cli.js in the project

so I checked my Spec file I had no errors.

describe('protractor page Object  training',function(){
    var obj= require("./PageObjectDemo.js");
    var d= require("./data.js");

    beforeEach(function() {
        obj.geturl();//the url on your test page is a method

      });


    it('Perform Simple Calculation ',function(){
    // write your code here!!!

        obj.firstnumber.sendKeys(d.datadrive.firstinput);//page of object properties
        obj.secondnumber.sendKeys(d.datadrive.secondinput);//page object properties

        obj.gobutton.click();


      //Jasmine Attribute Syntax toBe. Jasmine takes care of the promise 'resolve'internally

        expect(obj.result.getText()).toBe(d.datadrive.result);      
        //this confirm printout in console.

   obj.result.getText().then(function(text){
        console.log(text) 
     }) //end of console log message           


    })//end of it block

    afterEach(function () {
       console.log("If you can see this, test is completed. Well Done!!");
    });

So I checked the data spec file :

module.exports.datadrive= 
    {
    firstinput:"3",
    secondinput:"5",
    result: "8"


    }

console.log(datadrive.result);
