Any server listening on ports 1024 and below must initially be opened as root and not as an ordinary user. I'm guessing it is running as the user malinapi.
It is either that or you already have something running on port 80
I dono why I am getting this error please help

I cannot start the cli again until I delete the project folder. What is the problem here ?
An error will get generated when running:

Expected to get an app running on port localhost:8001, but the above error gets generated.
The reason is because it is trying to open a browser window from inside WSL terminal.
Instead, do the following:
vue ui --headless
This will avoid running the cmd.exe to open a browser and instead run the app on port 8001. You'll have to open a browser manually to http://localhost:8001
So, i tried to deploy my Express.Js app to my vps, but I get some error that refined to Error: getaddrinfo EAI_AGAIN undefined. The weird part is, it is doing just fine if I run this app on my localhost. Any body knows how to resolve this issue?
Here are the error log that I get.

I assume that by now you discovered the error, but in this particular case it seems that the variable you are using to setup ldap is not stated or resolves to undefined.
The proper way to do it according to the documentation is this:
var ldap = require('ldapjs');
var client = ldap.createClient({
url: 'ldap://127.0.0.1:1389'
});
