node.js - 将 node.js Web 应用程序部署到 Heroku 时出现 H10 应用程序崩溃错误

Question

我正在尝试在 Heroku 上部署我的 node.js Web 应用程序，但我不断收到“应用程序崩溃”错误。我已经尝试了我在互联网上找到的所有解决方案，但似乎没有一个有效。日志如下：

这是我的 server.js 文件中的相关代码：

const app = express()
const port = process.env.PORT || 5000;

const uri = process.env.ATLAS_URI;

const userRouter = require('./routes/user')
app.use('/user', userRouter)
const homepageRouter = require('./routes/home')
app.use('/homepage', homepageRouter)
const forumRouter = require('./routes/forum')
app.use('/forum', forumRouter)

app.listen(port, () => {
    console.log(`Server is running on port: ${port}`);
});

这是我的 ProcFile：

web:node src/index.js
web:node backend/server.js

这是我的 package.json 文件，它位于根目录中

      "last 1 safari version"
    ]
  },
  "proxy": "http://localhost:5000",
  "secure": "false"
}

这是后端文件夹中的 package.json 文件：

{
  "name": "backend",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "node server.js",

    "express": "^4.17.1",
    "mongoose": "^5.9.20"
  },
  "proxy": "http://localhost:5000"
}

我已经在 Heroku 控制台中设置了所需的配置变量，但 PORT 变量除外，因为 Heroku 应该在运行时创建自己的 PORT 变量。也许我的 package.json 文件中需要一些东西？我将不胜感激任何帮助。
