Q:

Property undefined

I have this error returned from the console: 
index.js:70 Uncaught TypeError: Cannot read property 'searchForm' of undefined
    at eval (index.js:70)

And I track down the error in the ES6 --> ES5 conversion by the Babel: 
_views_base__WEBPACK_IMPORTED_MODULE_2__["elements"].searchForm.addEventListener('submit', function (e) {

Index.js:
// always make sure you have the right directory 

// import field 
import Search from './models/Search'; 
// import all the function from the view 
import * as searchView from './views/searchView'
import {elements} from './views/base'; 

/* Global state of the app
    - Search obj 
    - current recipe obj
    - shopping list object
    - liked recipes
*/

// everytime we reload the app, it will be empty 
const state = {}
const controlSearch = async () =>{
    // 1) Get the query from the view 
    const query =  searchView.getInput;
    console.log(query);

    if(query){
        // 2) new search object and add it to state 
        state.search = new Search(query); // new instance of the search class 

        // 3) prepare UI for results 

        // 4) Search for recipes 
        await state.search.getResults();

        // 5) render result in the UI, reminder u got hit the search button 
        console.log(state.search.result);

    }
}
elements.searchForm.addEventListener('submit', e =>{
    e.preventDefault();
    controlSearch();
})

const search =  new Search('pizza');
console.log(search); 
search.getResults();

searchView.js:
// if we are in the current folder then it is simply base 
import {elements} from './base'; 
// return the input value from the field 
// implicit search 
export const getInput =() => elements.searchInput.value; 

base.js:
// all the DOM element will be in this class 
export const element = {
    searchForm: document.querySelector('.search'),
    searchInput: document.querySelector('.search__field')
}

Tracking down the error, I think everything is being defined and I don't seem to see how this error can happen. I am new to web-Dev, I hope this is not a bad question. I really need a more experienced mind to look at the error. Thanks a lot. 

A:

In your base.js....you are exporting element
export const element

where as in your index.js...you are importing elements
import {elements} from './views/base'; 

Change 'elements' to 'element' or vice cersa
