Node and MongoDB communication problem during valiadation and post route - node.js

Question

I have a plain node express webserver that send MongoDB Atlas a post request. I use mongooose.
Before do this there is some express-validators work.
Two API key used in this project. Thats enabled and work. Of course not share here...
I test with Postman.
This code from Node and MongoDB expert.
If i change MongoDB cluster not help.
I got two error:
Validation error: Invalid inputs passed, please check your data 422
If I comment out validation got different error:
Other error on post route: Creating place failed, please try again 500
app.js
const express = require('express');
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
const placesRoutes = require('./routes/places-routes');
const usersRoutes = require('./routes/users-routes');
const HttpError = require('./models/http-error');
const app = express();
app.use(bodyParser.json());
app.use('/api/places', placesRoutes); // => /api/places...
app.use('/api/users', usersRoutes);
app.use((req, res, next) => {
const error = new HttpError('Could not find this route.', 404);
throw error;
});
app.use((error, req, res, next) => {
if (res.headerSent) {
return next(error);
}
res.status(error.code || 500);
res.json({ message: error.message || 'An unknown error occurred!' });
});
mongoose
.connect('xxxx')
.then(() => {
app.listen(5000);
})
.catch(err => {
console.log(err);
});

Answer 1

Firstly use this middleware in app.js, and remove body-parser.
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
It parses your request and you get all values...

Answer 2

Only a plus ":" sign by title
wrong
{
"title:": "Empire State Building",
"description": "A very famous building in NY",
"address": "20 W 34th St, New York, NY 10001",
"creator": "u2"
}
and the good:
{
"title": "Empire State Building",
"description": "A very famous building in NY",
"address": "20 W 34th St, New York, NY 10001",
"creator": "u2"
}
