Problem with Mongoose + auth

import mongoose, { model, Schema } from 'npm:mongoose@^6.7';

const dinosaurSchema = new Schema({
  name: { type: String, unique: true },
  description: String,
  createdAt: { type: Date, default: Date.now },
  updatedAt: { type: Date, default: Date.now },
});

const Dinosaur = model('Dinosaur', dinosaurSchema);

// await mongoose.connect('mongodb://localhost:27017');

await mongoose.connect('mongodb://username:password@localhost:27017');

// Check to see connection status.
console.log(mongoose.connection.readyState);

console.log(await Dinosaur.find());
