Why the command “npm start” doesn’t work on my Electron framework project?

I’ve made a simple notes app using HTML, CSS and Javascript, and now i want to turn it into a desktop application, i’m using the Electron framework to achieve it, but for some reason i can’t launch the application for testing purposes.

i typed “npm start” on the code editor terminal to launch the application, but instead it outputs the following log:

> [email protected] start
> electron .

[17011:0428/235408.856171:ERROR:bus.cc(407)] Failed to connect to the bus: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory

Additional information (if useful).
the main.js file is on the root directory of the project, and the HTML, CSS and Javascript of the website is on a folder called “src” on the root directory, as this screenshot shows:

Main.js code:

const { app, BrowserWindow } = require('electron');

function createWindow() {
    const win = new BrowserWindow({
        width: 800,
        height: 600,
    });

    win.loadFile('src/index.html');
}

app.whenReady().then(createWindow);

app.on('window-all-closed', () => {
    if (process.platform !== 'darwin') app.quit();
})

script.js code (the code that saves the notes app text on browser):

var textarea = document.querySelector('textarea');

textarea.addEventListener("input", function () {
    var textWritten = textarea.value;
    localStorage.setItem("written", textWritten);
});

var written = localStorage.getItem("written");

if (written) {
    textarea.value = written;
}
