Cannot read properties of undefined "collectionName" - Mongoose.models - mongodb

Question

I'm trying to data in the Note collection from a local database of MongoDB using Mongoose with Nextjs and getting an error "Cannot read properties of undefined (reading 'note')"
Any ideas on what I am doing wrong?
import mongoose from 'mongoose';
const { Schema } = mongoose;
const NoteSchema = new Schema(
{
title: {
type: String,
maxlength: 60,
},
description: {
type: String,
maxlength: 200,
},
},
{ timestamps: true }
);
export default mongoose.models.note || mongoose.model('note', NoteSchema)
import dbConnect from "../../../lib/dbConnect"
import Note from "../../../models/Note"
export default async function handler(req, res) {
const { method } = req
await dbConnect()
if (method === 'GET') {
try {
const note = await Note.find({})
res.status(200).json({ success: true, data: note})
} catch (error) {
res.status(400).json({ success: false })
}
}
if (method === 'POST') {
try {
const note = await Note.create(req.body)
res.status(200).json({ success: true, data: note})
} catch (error) {
res.status(500).json(error)
}
}
}
import mongoose from 'mongoose'
const {MONGODB_URI} = process.env
let cached = global.mongoose
if (!cached) {
cached = global.mongoose = { conn: null, promise: null }
}
async function dbConnect() {
if (cached.conn) {
return cached.conn
}
if (!cached.promise) {
const opts = {
useNewUrlParser: true,
useUnifiedTopology:true,
bufferCommands: false,
}
cached.promise = mongoose.connect(MONGODB_URI, opts).then((mongoose) => {
return mongoose
})
}
cached.conn = await cached.promise
return cached.conn
}
export default dbConnect
I get the following
Unhandled Runtime Error
TypeError: Cannot read properties of undefined (reading 'note')

I was able to fix it by changing the export module
global.PizzaSchema = global.NoteSchema || mongoose.model('Note', NoteSchema);
export default global.NoteSchema;
