Question

我创建了一个可以在localhost上完美运行的MERN应用。当我将其部署到heroku时，它会构建和部署，但是当单击该站点时，它会显示一个JSON {error：'unauthorized access'}

我确实在heroku设置中设置了环境变量，我添加了mlab add。这是我的第一个全栈应用程序，但我被这个障碍绊倒了。

这是我的server.js文件

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser');
const cors = require('cors');
const dotenv = require('dotenv')
const path = require('path')


//  Configure the env file 
dotenv.config()


// Import routes
const transactions =  require('./routes/api/Transaction');
const users =  require('./routes/api/User');

// Instantiating the app variable
const app = express();


// Connecting to the mongodb server with mongoose odm
mongoose.connect(process.env.MONGODB_URI,{useNewUrlParser:true, useUnifiedTopology:true})
mongoose.set('useFindAndModify', false)


// Middleware/ Routes
app.use(bodyParser.urlencoded({extended:false}))
app.use(express.json())
app.use(cors())

app.use('/', users);
app.use('/api',transactions);


if (process.env.NODE_ENV === 'production'){
    app.use(express.static('client/build/'));
}

app.get('*', (req, res) => {
    res.sendFile(path.resolve(__dirname,'client','build','index.html'));
    });

// Port for listening to requests
const port = process.env.PORT || 8000;
app.listen(port, ()=>console.log(`Server running at port ${port}`));

这是我的package.json文件

我被困住了。我该怎么办？我在做什么错了？

ps：我使用npm作为软件包管理器，并使用github与heroku而不是heroku-cli集成

Heroku上的Mern部署未经授权
