Django and VueJS integration error. Error loading VueJS component to Django

I have created Django and VueJS integrated project using webpack_loader. Django runs at localhost 8000 and VueJS at 8080 port. But port 8000 gives me an error in console that GET http://0.0.0.0:8080/app.js net::ERR_ADDRESS_INVALID

as I am learning to integrate this two framework together, I followed a tutorial as mention below for this project

Thanks in advance

I have checked http://localhost:8080/app.js and it renders a large file, so how come port 8000 cannt connect with it ?

and I have done following changes too

in vue.config.js

change: baseUrl: “http://0.0.0.0:8080/",

to: baseUrl: “http://127.0.0.1:8080/",

and in settings.py change the CACHE value to not DEBUG
