Error("No Sequelize instance passed") No Sequelize instance passed - node.js

Question

Hello can somebody help me with this ? I was doing my controllers and I can access to my model like this "const { User } = require("../models/User");" but than when I send my request I had this message "TypeError: Cannot read property 'create' of undefined" so something was missing.
So I change my call model to this "const { User } = require("../models");".
And I went on my model index.js (so connection sequelize) and I add fs function and Objectif.key. After all those changes I have the error "No Sequelize instance passed".
So maybe somebody can help with this because I don't see the problem
So this is my model index.js
//sequelize importe
const fs = require("fs");
const path = require("path");
const Sequelize = require("sequelize");
const db = {};
const basename = path.basename(__filename);
let sequelize = new Sequelize("groupomania", "root", "root", {
host: "localhost",
dialect: "mysql",
});
sequelize
.authenticate()
.then(() => {
console.log("Connection has been established successfully!");
})
.catch((err) => {
console.log("Can't establish database connection:\n" + err);
});
fs.readdirSync(__dirname)
.filter((file) => {
console.log( file.indexOf(".") !== 0 && file !== basename && file.slice(-3) === ".js");
return (
file.indexOf(".") !== 0 && file !== basename && file.slice(-3) === ".js"
);
})
.forEach(file => {
const model = require(path.join(__dirname, file))(sequelize, Sequelize.DataTypes);
db[model.name] = model;
});
Object.keys(db).forEach((modelName) => {
if (db[modelName].associate) {
db[modelName].associate(db);
}
});
db.sequelize = sequelize;
db.Sequelize = Sequelize;
module.exports = db;
This is my model User.js
const { Model } = require("sequelize");
module.exports = (Sequelize, DataTypes) => {
class User extends Model {
toJSON() {
return {
...this.get(),
password: undefined,
};
}
}
User.init(
{
id: { type: DataTypes.UUID, defaultValue: DataTypes.UUIDV4 },
nom: { type: DataTypes.STRING, allowNull: false },
prenom: { type: DataTypes.STRING, allowNull: false },
email: {
type: DataTypes.STRING,
allowNull: false,
validate: { notNull: true, notEmpty: true, isEmail: true },
},
status: { type: DataTypes.STRING, allowNull: false },
password: { type: DataTypes.STRING, required: true },
},
{ Sequelize, tableName: "users", modelName: "User" }
);
return User;
};
My controllers/user.js
/*const bcrypt = require("bcrypt");
const jwt = require("jsonwebtoken");*/
const { User } = require("../models/User");
module.exports.signup = async (req, res) => {
try {
const user = await User.create({
nom: "Jp",
prenom: "remy",
email: "remy#gmail.fr",
password: "motdepasse",
});
res.status(200);
throw Error("erreur est survenu");
} catch (erreur) {
console.log(erreur);
res.status(200).json({ erreur });
}
};
My route user
const express = require("express");
const router = express.Router();
const userCtrl = require("../controllers/user");
router.post("/signup", userCtrl.signup);
/*router.post("/login", userCtrl.login);*/
module.exports = router;
Thank you for any help! :)

The answer was that on my model user the "S" of sequelize must have an s minus
