index.js

const path = require("path");
const express = require("express");
const exp = require("constants");
const dotenv = require("dotenv").config();
const port = process.env.PORT || 5001;
const app = express();
//enable body parser
app.use(express.json());
app.use(express.urlencoded({ extended: false }));

//set static folder
app.use(express.static(path.join(__dirname, 'pubic')));
app.use('/openai', require("./routes/openaiRoutes"));
app.listen(port, () => console.log(`Server started on port ${port}`));

我有一个index.js文件，在公共文件夹中有index.html文件。
我通过以下路径引用index.js中的index.html，但在端口5001上运行localhost时收到错误

浏览器错误
