I have made the handlebars config in my index.js that I think was made correctly, but I continue to get this error where my main.hbs dont get found

Here's my code:

const express = require('express');
const mysql = require('mysql2');
const bodyParser = require('body-parser');
const { engine } = require('express-handlebars');
const app = express();


app.engine("handlebars", engine())
app.set("view engine", "handlebars")
app.set("views", "./views")

app.get('/', (req,res) => {
  res.render('main')
})

app.listen(3000, () => {
  console.log('Servidor na porta 3000')
})

Project structure is built this way:

.
├── index.js
└── views
    ├── home.handlebars
    └── layouts
        └── main.handlebars

Complete log error
