Cannot read properties of undefined (reading 'findOne') in nextauth - reactjs

Question

Hi I building login form and doing authentication with using nextjs , nextauthjs and mysql
these are my codes .
import NextAuth from "next-auth";
import CredentialsProvider from "next-auth/providers/credentials"
import { query } from "../getdata";
import axios from "axios";
import { Users } from "../../../../server/models/Users";
import mysql from 'mysql2';
export default NextAuth({
session: {
strategy: 'jwt',
},
callbacks: {
async jwt({ token, user }) {
if (user?.id) token.id = user.id;
return token;
},
async session({ session, token }) {
if (token?.id) session.user.id = token.id;
return session;
},
},
providers: [
CredentialsProvider({
name: "credentials",
credentials: {
username: {
label: "username",
type: "text",
placeholder: "johndoe#test.com",
},
password: { label: "Password", type: "password" },
},
authorize: async (credentials) => {
const user = await Users.findOne({ where: { username: credentials.username } });
console.log()
// database look up
if (
credentials.username === user.username &&
credentials.password === user.password
) {
return {
name: "John",
email: "johndoe#test.com",
};
} else {
throw new Error(errorMessage);
}
},
}),
],
});
I am getting this error when I am logging in
Cannot read properties of undefined (reading 'findOne')
Here are data for /models/Users i used this in next auth js.
once i used these code in express there its worked fine same thing i am doing in nextauth but it gives me error
module.exports = (sequelize, DataTypes) => {
const Users = sequelize.define("Users", {
username: {
type: DataTypes.STRING,
allowNull: false,
},
email: {
type: DataTypes.STRING,
allowNull: false,
},
password: {
type: DataTypes.STRING,
allowNull: false,
},
role: {
type: DataTypes.STRING,
allowNull: false,
},
});
return Users;
};
