In my project that I created with Electron, there is a server side written in NodeJS and a frontend side written in ReactJS. When I built the project, ran setup.exe and installed the application, I saw that the server side was not working. how do I fix this? here is electron.js ;

const electron = require("electron");
const path = require("path");
const { exec } = require("child_process");
const isDev = require("electron-is-dev");

const { app, BrowserWindow } = electron;

let mainWindow;

function createWindow() {
    mainWindow = new BrowserWindow({
        width: 1000,
        height: 800,
        icon: path.join(__dirname, "../assets/logo.ico"),
        webPreferences: {
            nodeIntegration: true,
            contextIsolation: false,
        },
    });

    mainWindow.loadURL(
        isDev
            ? "http://localhost:3000"
            : `file://${path.join(__dirname, "../build/index.html")}`
    );

    mainWindow.on("closed", () => (mainWindow = null));
}

app.on("ready", () => {
    const serverPath = isDev 
        ? path.join(__dirname, "../src/server.js")
        : path.join(process.resourcesPath, "server.js");

    exec(`node ${serverPath}`, (error, stdout, stderr) => {
        if (error) {
            console.error(`Error starting server: ${error.message}`);
            console.error(`Error code: ${error.code}`);
            console.error(`Error signal: ${error.signal}`);
            return;
        }
        if (stderr) {
            console.error(`stderr: ${stderr}`);
        }
        console.log(`stdout: ${stdout}`);
    });

    createWindow();
});

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

app.on("activate", () => {
    if (mainWindow === null) {
        createWindow();
    }
});

and here is my package.json ;
