What is the output of this Mongoose code

if validation fails? const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/db');

new mongoose.Schema({
  age: {
    type: Number, min: 18
  }
}

mongoose.model('Model', schema);
async function run() {
  try {
    await Model.create({
      age: 17
    }
    );
  }
  catch (err) {
    console.log('Validation error');
  }
}
