I am trying to connect Mongoose with my nodejs environment but it is giving an unexpected error. Before I was able to connect with mongoose with the same commands, But for few days its giving error
index.js file
import express from 'express';
import mongoose from 'mongoose';
import User from './User.js';
const app = express()
const port = 5050
const connection_url ="mongodb+srv://admin:'passwordhere'@cluster0.hcbbvuo.mongodb.net/?retryWrites=true&w=majority";
app.use(express.json())
mongoose.connect(connection_url,{
useNewUrlParser: true,
useUnifiedTopology: true,
family: 4, })
mongoose.connection.on('connected',()=>{ console.log("Connected to DB") })
app.post('/user',(req,res)=>{
console.log('Creating new user')
const u = { "name":"Yash", "email":"yash@gmail.com", "password":"yash", "wins":0, "losses":0 }
User.create(u,(err,data)=>{
if(err)
console.log(err)
else
console.log(data)
})
})
app.listen(port,()=>{
console.log('Listening on port :',port) })
userSchema file
import mongoose from 'mongoose';
const User = mongoose.Schema({
name: { type: String, required: true },
email: { type: String, required: true, unique:true },
password: { type: String, required: true },
wins: { type: Number,default:0},
losses: { type: Number,default:0},
});
export default mongoose.model('User',User)

Few things :
I have put '0.0.0.0/0' as IP in the network access on the mongoose, so its not the problem with IP
I tried to put the driver code that mongoose gives to connect with the app
const uri = "mongodb+srv://admin:<password>@cluster0.hcbbvuo.mongodb.net/?retryWrites=true&w=majority"; const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true, serverApi: ServerApiVersion.v1 }); client.connect(err => { const collection = client.db("test").collection("devices"); // perform actions on the collection object client.close(); });
Instead of mongoose.connect It has worked but when calling POST or GET request to create user or get any data it is giving this error
Error
