File: requirejs-config

Path

app/design/frontend/SimpleMagento/CustomTheme/requirejs-config.js

var config = {
   paths: {
    slickSlider: 'js/slick.min'
   },
   shim: {
     slickSlider: {
        deps: ('jquery')
      }
   }
};

I added slick.min.js in

app/design/frontend/SimpleMagento/CustomTheme/web/js/slick.js

but error is still there, everytime I reload the page its showing new error

Here is the few screenshot of error, I think its conflicting with core js.
