Build never end with MongoDB Atlas Integration

Here is my MONGO_URI: mongodb+srv://vercel-admin-user:(...)@cluster0.xbldt.mongodb.net/myFirstDatabase?retryWrites=true&w=majority

Here is the db.js:

const mongoose = require('mongoose');

const connectDB = async () => {
    try {
        const conn = await mongoose.connect(process.env.MONGO_URI, {
            useNewUrlParser: true,
            useUnifiedTopology: true,
        });
        console.log(`MongoDB Connected: ${conn.connection.host} DB: ${conn.connection.db.databaseName}`);
    } catch (err) {
        console.error(`Error: ${err.message}`);
        process.exit(1); // Exit process with failure
    }
};

module.exports = connectDB;

My IP Access list is set to 0.0.0.0/0 in Atlas.

Why my deployment's build step do not complete within the maximum of 45min?

Hi , welcome to the Vercel Community!

Thanks for sharing the project details. I checked your build logs and the project. It seems like you are running node server.js, which is used to run Node.js on servers like EC2. Because Vercel is a serverless platform this command will not work and lead to failed builds.

I'd encourage you to read the https://vercel.com/guides/using-express-with-vercel and update the application code to work with Vercel. These changes should be relatively smaller. You can also look at the Express example solution that works on Vercel.

I hope this was helpful.

Hi,

I added vercel.json file and now it's working:

{
  "version": 2,
  "builds": [
   { "src": "server.js","use": "@vercel/node" },
   { "src": "package.json", "use": "@vercel/static-build", "config": {"distDir": "dist"} }
  }
  ],
  "routes": [
   {
    "src": "/(.*)",
    "dest": "/server.js"
   }
  ]
 }

The server is here : https://serveur-react.vercel.app/

Thanks!
