File not Found - But I dont have such file in this folder?

I went to test my JS code with "npm run sourceFile.js".

However npm reports it cannot find a file called "pacakge.json", BUT I never created the file or used in my code.

So I don not know why npm is reporting such file. And;

• I believe this is causing my other problem where my JS function is not being define (you can see this in the screen shot provided).

Here is my JS code:

/*
    Page Structure
*/
import { top_container_config, middle_container_config, bottom_container_config} from './page_structure_config.js';

//------------------------------------------------------------------------------

function createDOMelement(element_, attributues_){
  var elem_ = document.createElement(element_);
  var k;
    for (k in attributues_){
      elem_.setAttribute(k,attributues_[k]);
  }
  return elem_;
}

//------------------------------------------------------------------------------
function topConainter(){
  var _container = "top_container";

}

//------------------------------------------------------------------------------

function middleContainer(){
  var _container_ID = "middle_container";
  var _columns = [];
  var _navVar;
  var _nv_items =[];

  //Columns
  for(var col = 0; col < middle_container_config.mc_columns.num; col++){
    _columns.push(createDOMelement("div",middle_container_config.mc_columns._DOM_));
  }

  //My Nav Var
  _navVar =  createDOMelement("div", middle_container_config.nav_stack._DOM_);

  //Inside my Nav Var
  for(var nv_i = 0; nv_i < middle_container_config.nav_stack_items.num; nv_i++){
    _nv_items.push(createDOMelement("div",middle_container_config.nav_stack_items._DOM_));
  }


  //JOIN ALL ELEMENT  - Inside OUt
  for (var a =0; a<_nv_items.length; a++){
    _navVar.appendChild(_nv_items[a]);
  }

  //Append NavVar to first column of the middle_container
  _columns[0].appendChild(_navVar);

  //add to DOM
  for(var b=0; b<_columns.length; b++){
    document.getElementById(_container_ID).appendChild(_columns[b]);
  }

  console.log(document.getElementById(_container_ID));

}

//------------------------------------------------------------------------------

function bottomContainer(){
  var _container = "bottom_container";

}

Here is picture of my npm output:

I run my npm command as the following:

npm run page_structure.js
