On sequelize, "include" of "findOne" not working

I made a simple test that is to search for an address (no matter where it is) and retrieve the user who is linked to that address.

Here are my Models:

user.js

module.exports = function(sequelize, DataTypes) {
    return sequelize.define('User', {
        id: {
            type: DataTypes.INTEGER(10).UNSIGNED,
            allowNull: false,
            field: 'id',
            //primaryKey: true,
        },
        name: {
            type: DataTypes.STRING,
            allowNull: false,
            field: 'name',
        },
    }, {
        freezeTableName: true,
        tableName: 'user',
        createdAt: false,
        updatedAt: false,
        classMethods: {
            associate: function(models) {
                models.User.hasMany(models.UserAddress, { foreignKey: 'userId' });
            },
        },
    });
};

user_address.js

module.exports = function(sequelize, DataTypes) {
    return sequelize.define('UserAddress', {
        id: {
            type: DataTypes.INTEGER(10).UNSIGNED,
            allowNull: false,
            field: 'id',
        },
        userId: {
            type: DataTypes.INTEGER(10).UNSIGNED,
            allowNull: false,
            field: 'user_id',
        },
        title: {
            type: DataTypes.STRING,
            allowNull: true,
            field: 'title',
        },
        address: {
            type: DataTypes.STRING,
            allowNull: true,
            field: 'address',
        },
    }, {
        freezeTableName: true,
        tableName: 'user_address',
        createdAt: false,
        updatedAt: false,
        classMethods: {
            associate: function(models) {
                models.UserAddress.hasOne(models.User, { foreignKey: 'id' });
            },
        },
    });
};

And here is my test file:

db.UserAddress.findOne({
    include: [
        { model: db.User },
    ],
}).then(function(address) {
    console.log('------------------------------ User by "include"');
    console.log('Address title: '+address.title);
    if(address.user !== undefined) {
        console.log('User name: '+address.user.name);
    } else {
        console.log('User name: NO USER');
    }
    console.log('');
    address.getUser().then(function(user) {
        console.log('------------------------------ User by "getUser"');
        console.log('Address title: '+address.title);
        console.log('User name: '+user.name);
        console.log('');
    });
});

I do a query with two tests:

• The first aims to recover the user directly via the variable "user", so thanks to "include" of the request.


• And the other also retrieve the user but this time via "getUser()".

Here is the result:

$ node test.js
Executing (default): SELECT `UserAddress`.`id`, `UserAddress`.`user_id` AS `userId`, `UserAddress`.`title`, `UserAddress`.`address`, `User`.`id` AS `User.id`, `User`.`name` AS `User.name` FROM `user_address` AS `UserAddress` LEFT OUTER JOIN `user` AS `User` ON `UserAddress`.`id` = `User`.`id` LIMIT 1;
------------------------------ User by "include"
Address title: Home
User name: NO USER

Executing (default): SELECT `id`, `name` FROM `user` AS `User` WHERE (`User`.`id`=1);
------------------------------ User by "getUser"
Address title: Home
User name: Valentin

One can observe that it is impossible to retrieve the result via "include". The error is visible in the log of SQL:

LEFT OUTER JOIN `user` AS `User` ON `UserAddress`.`id` = `User`.`id`

While the correct answer should have been:

LEFT OUTER JOIN `user` AS `User` ON `UserAddress`.`user_id` = `User`.`id`

So my question is, what is the configuration to put in my Model or my request for the result to be correct with "include" ?

Thank you.
