在IIS上部署NodeJS+React应用遇HTTP 200错误求助

我尝试在虚拟机的IIS上部署NodeJS和React Web应用，但始终无法成功。我已尝试网上能找到的所有解决方案，仍遭遇HTTP 200错误（错误截图：HTTP 200错误截图）。

以下是运行在3000端口的server.js文件：

import cors from 'cors';
import express from "express";
import sql from "mssql";
import { PORT } from './config.js';
import inventoryRouter from './routes/inventoryRoute.js';
import transferRouter from './routes/transferRoute.js';
import orderRouter from './routes/orderRoute.js';
import path from 'path';
import { fileURLToPath } from 'url';

const sqlConfig = {
user: "testuser",
password: '1234',
// server: 'DESKTOP-VN9PRPU\\SQLEXPRESS', // or 'localhost' for a local instance
server: 'YIHANG\\SQLEXPRESS',
// server: 'MDPADMIN\\SQLEXPRESS',
database: 'inventory',
driver: 'msnodesqlv8',
options: {
    // encrypt: false,
    // trustServerCertificate: true,
    trustedConnection: false,
    encrypt: false
}
};

const app = express();

const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);

app.use(cors());
app.use(express.json());
app.use(express.urlencoded({ extended: true }));

app.use(express.static(path.join(__dirname, '../frontend/dist')));

let pool;

async function connectDB() {
try {
    pool = await new sql.connect(sqlConfig);
    app.listen(PORT, () => { //PORT is 3000
        console.log("app is running le");
    })
    console.log("connected le");
} catch (err) {
    console.error('error is ', err);
}
}

app.use((req, res, next) => {
req.pool = pool;
next();
})


app.use('/inventory', inventoryRouter);
app.use('/transfers', transferRouter);
app.use('/orders', orderRouter);

app.use('/images', express.static('images'))


connectDB();

另外附上我的web.config文件截图：web.config截图。

更新：我已尝试以下解决方案但均无效：

• 下载iisnode和rewrite模块
• 为IIS_IUSRS、IUSR及应用池实例赋予完全权限
• 在iisnode的web.config中设置devErrosEnabled和LoggingEnabled为false
• 将应用目录直接移至C盘

恳请各位提供解决建议！
