[nodemon] restarting due to changes...
[nodemon] starting `node index.js`

This is the code of the module (btw dont mind but th "ok" its for testing.

const router = require("express").Router();

const User = require("../models/User")

//REGISTER
router.get("/register", async (req,res)=>{
const user = await new User({
    username:"john",
    email:"john@gmail.com",
    password:"123456"
})

await user.save();
res.send("ok");
});

module.exports = router

the syntax is right, needed to format it for containing on the "code" on the question. Thanks in advance, Francesco

    You are getting the error `MongooseError: Operation 'users.insertOne()' buffering timed out after 10000ms`. What exactly do you not understand? – JSON Derulo Sep 06 '21 at 08:39
  • check your `mongoose.connect()` function for errors - mongoose can't connect to the database. – Taxel Sep 06 '21 at 08:39

You are trying to call the model without even establishing a connection with the database. You need to use async/await with connect() or createConnection().
