I am working on the Front End production video and after completing all the steps I receive the "Cannot GET / " error after inspecting the element in the browser it says : GET http://localhost:8000/ 404 (Not Found) . I don't have anything else to go on. I have gone through the video 3 times I am not seeing what is causing the issues. THX
"server": "npm run watch --prefix server",
"client": "npm start --prefix client",
"watch": "npm run server & npm run client",
I added these three lines of code into my root package.json
and when running npm run watch
in the terminal, only the server comes up and the client won't start. And I have this warning in the chrome:
VM86:5 crbug/1173575, non-JS module files deprecated.
my node version is 18.17.1
Has anyone else faced this problem?

Hello, how are you?
What is your email address?
i am having troubles populating the destination exo planets am using a versio of node which is encouraging me to use es6 modules not the common js but the issue has been heart breaking i have tried all i knew but its failing some immediate help will be appreciated
Hi Odziem,
I have built the application on docker and cannot see the client page on the 8000 port. Please help me with how to view the client page from docker. However, I can run applications individually on my machine on ports 3000 & 8000.
Getting Error: when hitting URL:
http://192.168.0.106:8000/
Error: ENOENT: no such file or directory, stat '/app/server/public/index.html'
It will be great if you write a docker-compose file for the client & server.
I really appreciate any help you can provide.
but issues keep on rising using newer versions of node as it doesnt support old js some help please i have been stuck for days but the majoe issuw is loading data on start up on the front end here is my planets.model.mjs
