Sequalize association fails (BelongsTo) NodeJs Sequalize - mysql

Question

Trying to work with sequalize association ( belongsTo and hasMany() ) but when i tries to query findAll with include the Model which was associated it fails by saying Models are not associated.
User Model
const {DATE, STRING, INTEGER} = require("sequelize");
const {USER} = require("../config/db.config");
module.exports = (sequelize, Sequelize) => {
const User = sequelize.define("Users", {
id: {
primaryKey: true, type: INTEGER, required: true, autoIncrement: true
}, phoneNumber: {
type: STRING, required: true, unique: true
}, firstname: {
type: STRING, required: true
}, middlename: {
type: STRING, required: false
}, region: {
type: STRING, required: true
}, district: {
type: STRING, required: true
}, street: {
type: STRING, required: true
}, lastname: {
type: STRING, required: true,
}, 'type': {
type: STRING, required: true,
}, email: {
type: STRING, required: true, unique: true
}, status: {
type: Sequelize.ENUM("ACTIVE", "NOT-ACTIVE", "SUSPENDED"), defaultValue: "NOT-ACTIVE",
}, createdAt: {
type: DATE,
}, updatedAt: {
type: DATE,
}
});
User.associate = function (models) {
User.hasMany(models.Students, {foreignKey: 'userId', as: 'user'});
}
return User;
};
Student Model
const {DATE, STRING, INTEGER} = require("sequelize");
module.exports = (sequelize, Sequelize) => {
const Student = sequelize.define("Students",
{
id: {
primaryKey: true, type: STRING, required: true
}, userId: {
type: INTEGER, required: true,
}, status: {
type: Sequelize.ENUM("ACTIVE", "NOT-ACTIVE", "SUSPENDED"), defaultValue: "NOT-ACTIVE",
},
level: {
type: STRING, required: true,
}, createdAt: {
type: DATE,
}, updatedAt: {
type: DATE,
}
});
Student.associate = function (models) {
Student.belongsTo(models.Users, {foreignKey: 'userId', as: 'user'})
Student.belongsToMany(models.Classes, {through: 'StudentClass',})
}
return Student;
};
I have tried to query them by using the bellow function but i got nothing
function getAllStudents() {
Student.findAll({include: [{model: User, as: 'user', required: true}]}).then(value => {
console.log(value)
return value;
}).catch(reason => {
console.error(reason)
})
}
But i get the following
Result i get
