Not able to send post request to my express API - node.js

Question

I am sending a post request to my Heroku API, but receiving nothing in return.
This is where I am making the request:
const [ user, setUser] = useState({
email:"",
password:""
})
const handleChange = e => {
const { name, value } = e.target
setUser({
...user,
[name]: value
})
}
const login = () => {
axios.post("https://<myherokuapp>/login", user)
.then(res => {
alert(res.data.message)
setLoginUser(res.data.user)
navigate("/")
})
}
This is the body of the request:
app.post("/login", (req, res)=> {
const { email, password} = req.body
User.findOne({ email: email}, (err, user) => {
if(user){
if(password === user.password ) {
res.send({message: "Login Successfull", user: user})
} else {
res.send({ message: "Password didn't match"})
}
} else {
res.send({message: "User not registered"})
}
})
})
app.post("/register", (req, res)=> {
const { name, email, password} = req.body
User.findOne({email: email}, (err, user) => {
if(user){
res.send({message: "User already registerd"})
} else {
const user = new User({
name,
email,
password
})
user.save(err => {
if(err) {
res.send(err)
} else {
res.send( { message: "Successfully Registered, Please login now." })
}
})
}
})
})
This is the index.js running on heroku:
import express from "express"
import cors from "cors"
import mongoose from "mongoose"
const app = express();
const port = process.env.PORT || 9002;
app.use(express.json())
app.use(express.urlencoded())
app.use(cors())
mongoose.connect("mongodb+srv://<myDbLink>.mongodb.net/?retryWrites=true&w=majority", {
useNewUrlParser: true,
useUnifiedTopology: true
}, () => {
console.log("DB connected")
})
const userSchema = new mongoose.Schema({
name: String,
email: String,
password: String
})
const User = new mongoose.model("User", userSchema)
//Routes
app.post("/login", (req, res)=> {
const { email, password} = req.body
User.findOne({ email: email}, (err, user) => {
if(user){
if(password === user.password ) {
res.send({message: "Login Successfull", user: user})
} else {
res.send({ message: "Password didn't match"})
}
} else {
res.send({message: "User not registered"})
}
})
})
app.post("/register", (req, res)=> {
const { name, email, password} = req.body
User.findOne({email: email}, (err, user) => {
if(user){
res.send({message: "User already registerd"})
} else {
const user = new User({
name,
email,
password
})
user.save(err => {
if(err) {
res.send(err)
} else {
res.send( { message: "Successfully Registered, Please login now." })
}
})
}
})
})
app.get("/",(req,res)=>{
res.send("get is working")
})
app.listen(port,() => {
console.log("BE started at port")
})
When I tried in my localhost , it was working fine , but now it is giving me an error user is not registered , even when I have the user in my database. Please help me solve this problem , this is the first time I am using heroku with nodejs.

Your route code is correct but the approach of hosting a website on Heroku is wrong, you should need to connect DB with Atlas Cluster for more detail and follow up on the official documentation Host Website on Heroku that uses Mongodb
