app.js file is as shown below:

app.use(bodyParser.json())
app.use(express.static(path.join(__dirname, '../dist')))
const message = require('./models/message')
app.get('/api/chat', (req, res) => {
    Message.find(  ).then(rec => {
        if(rec) {
            console.log("Yo");
            res.send(rec)
            
        } else {
            console.log("Successful !!!");
            res.send([])
    // res.json({
    //     message:"hellu",
         }
        })
    
})
app.post('/api/chat', (req, res) => {
  const newMessage = new Message({
      _id: mongoose.Types.ObjectId(),
      message: req.body.message,
      user: 'user'
    })
    newMessage.save().then(rec => {
        if(rec) {
            res.send(rec)
        } else {
            res.send([])
        }
    })
})
app.get('*', (req, res) => {
    res.sendFile(path.join(__dirname, '../dist/index.html'))
})
app.listen(3000, () => console.log('Listening on port 3000....'))

Replace your Message variable to message. You imported with a different names and using with a different names. — Prathamesh More

The error lies in these 3 lines:

const message = require('./models/message')
app.get('/api/chat', (req, res) => {
    Message.find(  ).then(rec => {

Had forgot to capitalize message..fixed the issue by rewiting:

const Message = require('./models/message')
app.get('/api/chat', (req, res) => {
    Message.find(  ).then(rec => {

Message.find is not a function
