After latest update to ionic 3.6.0 i am getting error during app run. in chrome console it says `Uncaught ReferenceError: webpackJsonp is not defined`

i have followed this post [https://stackoverflow.com/questions/44988166/ionic-2-referenceerror-webpackjsonp-is-not-defined](https://stackoverflow.com/questions/44988166/ionic-2-referenceerror-webpackjsonp-is-not-defined) and added:

```auto
 <!-- all code from node_modules directory is here -->
  <script src="build/vendor.js"></script>

```

but when run `ionic cordova run android --prod` the script code removed automatically from my index file and getting same error in build.

I HAVE added it to sec/index.html and still see this error.  
Why are there sooo many bugs and bad documentations here? I am loosing days, if not weeks because of poor change management, documentation and bugs

After add to `src/index.html` you can try ionic `run` or `build`. it will solve the issue. hence you can post issue if still getting ?

Ionic community working to update documentations and fixing continue basis.
