Got error on blog.js when inserting documents (Section 26/ Insert Documents)

[m-tonon]

I was getting this error:

BSONTypeError: Argument passed in must be a string of 12 bytes or a string of 24 hex characters or an integer
    at new BSONTypeError (/home/mtonon/Web Dev/mongodb-page/node_modules/bson/lib/error.js:41:28)
    **at new ObjectId** (/home/mtonon/Web Dev/mongodb-page/node_modules/bson/lib/objectid.js:67:23)
    at /home/mtonon/Web Dev/mongodb-page/routes/blog.js:28:20

Then I found a solution on forums, just use .trim() on const authorId to remove any extra blank space:

router.post('/posts', async function(req,res){
  const authorId = new ObjectId(req.body.author.trim()); 

If someone is getting the same error, this worked for me!

Is not working for me

const express = require('express');

const mongodb = require('mongodb');
const db = require('../data/database');

const ObjectId = mongodb.ObjectId;

const router = express.Router();

router.get('/',function(req, res) {

res.redirect('/posts');
});

router.get('/posts', function(req, res) {
res.render('posts-list');
});

router.get('/new-post', async function(req, res) {
//Establish acces to the table authors
const authors = await db.getDb().collection('authors').find().toArray();
console.log(authors);
res.render('create-post', {authors:authors});
});

router.post('/posts', async function(req, res) {
// const authorId = new ObjectId(req.body.author);
const authorId = new ObjectId(req.body.author.trim());

const author = await db.getDb().collection('authors').findOne({_id: authorId})
const newPost = {
title: req.body.title,
summary: req.body.summary,
body: req.body.content,
date: new Date(),
author: {
id: author,
name: author.name,
email: author.email
}
};
const result = db.getDb().collection('posts').insertOne(newPost);
console.log(result);
res.redirect('/posts');

});

module.exports = router;
