TypeError: la imagen no es un constructor const newImg = nueva imagen ({

cuando trato de cargar una imagen y guardar su título, descripción y nombre de archivo en la base de datos, aparece este error, por favor ayuda, estoy usando NodeJS y mongoose. por favor ayuda para resolver este problema y, si es posible, una breve explicación del problema.

 const newImg = new Image({ ^

TypeError: la imagen no es un constructor

este es el codigo

 const path = require('path'); const { randomNumber } = require('../helpers/libs.js'); const fs = require('fs-extra'); const ctrl = {}; const { Image, Comment } = require('../models/'); ctrl.index = async (req, res) => { let viewModel = { image: {}, comments: [] }; const image = await Image.findOne({filename: { $regex: req.params.image_id }}); if (image) { image.views = image.views + 1; viewModel.image = image; image.save(); const comments = await Comment.find({image_id: image._id}) .sort({'timestamp': 1}); viewModel.comments = comments; viewModel = await sidebar(viewModel); res.render('image', viewModel); } else { res.redirect('/'); } }; ctrl.create = async (req, res) => { const imgUrl = randomNumber(); console.log(imgUrl); const imageTempPath = req.file.path; const ext = path.extname(req.file.originalname).toLowerCase(); const targetPath = path.resolve(`src/public/upload/${ imgUrl }${ ext }`); if (ext === ".png" || ext === ".jpg" || ext === ".jpeg" || ext === ".gif") { await fs.rename(imageTempPath, targetPath); const newImg = new Image({ title: req.body.title, description: req.body.description, filename: imgUrl + ext, }); const imageSave = await newImg.save(); } res.send('recibido'); };

Aquí está el esquema

 const mongoose = require('mongoose'); const { Schema, model } = mongoose; const path = require('path'); const ImageSchema = new Schema({ title: { type: String }, description: { type: String }, filename: { type: String }, views: { type: Number, default: 0 }, likes: { type: Number, default: 0 }, timestamp: { type: Date, default: Date.now } }); ImageSchema.virtual('uniqueId') .get(function () { return this.filename.replace(path.extname(this.filename), ''); }); module.exports = mongoose.model('Image', ImageSchema);

Por favor ayuda
