Having trouble querying my database with a join table in mySQL, can someone please help?

So I'm trying to figure out how to query my database with a join table, I can do it raw in the mySql terminal but I'm having a hard time doing via a function call.
Here's my tables I've created
const Review = db.define('Review', { id: { type: Sequelize.INTEGER, allowNull: false, autoIncrement: true, primaryKey: true, }, likes: { type: Sequelize.INTEGER, }, dislike: { type: Sequelize.INTEGER, }, id_user: { type: Sequelize.INTEGER, foreignKey: true, }, text: { type: Sequelize.STRING(2020), }, id_web: { type: Sequelize.INTEGER, foreignKey: true, }, id_keyword: { type: Sequelize.INTEGER, foreignKey: true, }, date: { type: Sequelize.DATE, }, }); const Users = db.define('Users', { id: { type: Sequelize.INTEGER, allowNull: false, autoIncrement: true, primaryKey: true, }, username: { type: Sequelize.STRING(50), }, serial: { type: Sequelize.STRING(100), }, bio: { type: Sequelize.STRING(1000), }, image: { type: Sequelize.STRING(250), }, }); 
All I'm trying to do right now is get the Review likes, dislikes, text and the actual username from the Users table.
I'm doing this successfully in the mySql terminal doing
mysql> SELECT likes, dislike, text, username FROM Reviews INNER JOIN Users ON Reviews.id_user = Users.id; +-------+---------+------------------------------------------------------------+----------------+ | likes | dislike | text | username | +-------+---------+------------------------------------------------------------+----------------+ | 0 | 0 | THIS IS JUST A TEST REVIEW | JOHN DOE | | 0 | 0 | THIS IS A SECOND TEST REVIEW TO SEE IF APPLE.COM IS FOUND | JOHN DOE | +-------+---------+------------------------------------------------------------+----------------+ 2 rows in set (0.00 sec) 
But my database function, and all the examples running online are breaking my code.
Here's what I have at the MOMENT but I know this is wrong.
(Note that Keyword is a separate table that stores hash tag values for articles, this is working just fine)
Const findArticleByKeyWord = (keyword) => { return Keyword.findOne({ where: { keyword } }).then((data) => { if (data === null) { console.log('no keyword found'); return; } else { return Review.findAll({ where: { id_keyword: data.id, include: [ { model: Users, as: 'Name', id_user: Users.id, }, ], }, }) .then((data) => { console.log(typeof data); console.log(data); return data; }) .catch((err) => console.log(err, 'SOMETHING WENT WRONG')); } }); }; 
I keep getting errors that say "invalid value: model"
But all the examples I'm finding online are using something like this?

MySQL Problem (JOIN)

Hi!
I am trying to save dates for a fictional car rental service. I made three tables: customers, vehicles and rent.
I have my details about the cars and customers in their tables but if i want to save information like:
"Tom rents the Mercedes on 09.01.2020 and on the 06.03.2020 or Mary rents the Renault at 13.2.2020"
how do I do that, like how do I combine the information about those two tables, store it in the third one and update it? Because with my "solution" my information does not get passed by:

create database if not exists autovermietung_markovic; use autovermietung_markovic; create table if not exists mieten( mietvertragsNr int primary key auto_increment, datum date, kndNr int, kennzeichenID int, first_name varchar(200), marke varchar(200)); create table if not exists kunden( kndNr int primary key auto_increment, first_name varchar(200), last_name varchar(200), gebDat date, mietvertragsNr int); create table if not exists fahrzeuge( kennzeichenID int primary key auto_increment, kennzeichen varchar(200), farbe varchar(200), marke varchar(200), typ varchar(200), mietbeitrag int, mietvertragsNr int); ALTER TABLE mieten ADD CONSTRAINT FK_kndNr foreign key (kndNr) references kunden(kndNr) ON UPDATE CASCADE; ALTER TABLE mieten ADD CONSTRAINT FK_kennzeichen foreign key (kennzeichenID) references fahrzeuge(kennzeichenID) ON UPDATE CASCADE; ALTER TABLE kunden ADD CONSTRAINT FK_mietvertrag foreign key (mietvertragsNr) references mieten(mietvertragsNr) ON UPDATE CASCADE; ALTER TABLE fahrzeuge ADD CONSTRAINT FK_mietvertrag2 foreign key (mietvertragsNr) references mieten(mietvertragsNr) ON UPDATE CASCADE; insert into fahrzeuge(kennzeichen, marke, typ, farbe, mietbeitrag) values('MD2345', 'Renault', 'Clio', 'Rot', 50), ('W9854', 'Mercedes', 'G Klasse', 'schwarz', 90), ('KO7865', 'BMW', 'M3', 'schwarz', 80), ('W8971F', 'VW', 'Passat', 'dunkelgrün', 80), ('W986', 'Tesla', 'Model 3', 'silber', 120); insert into kunden(first_name, last_name, gebDat) values('Tom', 'Riddle', '1971-01-12'), ('Peter', 'Smith', '1982-09-30'), ('Mary', 'Miller', '2000-01-04'); insert into mieten(datum, kndNr, kennzeichenID) values('2019-12-09', 1, 1), ('2020-01-05', 1, 1), ('2020-01-18', 2, 1), ('2020-02-13', 3, 1), ('2020-02-15', 2, 3), ('2020-01-09', 1, 2), ('2020-03-06', 1, 2); SELECT kunden.first_name, fahrzeuge.marke INTO @mieten.first_name, @mieten.marke FROM kunden JOIN fahrzeuge ON kunden.mietvertragsNr = fahrzeuge.mietvertragsNr; 
Result for the last query:

mysql> select kunden.first_name, fahrzeuge.marke from kunden join fahrzeuge on kunden.mietvertragsNr = fahrzeuge.mietvertragsNr; Empty set (0.00 sec)
