Uncaught ReferenceError: webpackJsonp in Vue Js - vue.js

Question

I have suddenly started hitting Uncaught ReferenceError: webpackJsonp in Vue Js. I am fairly new to Js and have just started with Vue applications. I tried the various solutions that were mentioned in the Git and stackoverflow but they have not worked. Can someone help me out.
To give some context, the issue suddenly appeared without having made much of a change. The code is working when it was in the state earlier but making any change in the components even modifying the css has started causing the issue.
Based on what I read about the issue, it is supposed to be controlled by the webpack.prod.conf.js (Attached mine below). Incase any other info is needed please let me know.

The entry points are missing in the configuration, i.e. you are not informing webpack from where the application should start.
Also this issue is happening because you have mentioned vendor
