createdAt cannot be an array or an object - node.js

Question

Can someone help me I'm having problems inserting a record in the database with sequelize, created_at and updated_at are automatically filled and this is with this error:
"name": "SequelizeValidationError",
"errors": [
{
"message": "createdAt cannot be an array or an object",

},
"validatorKey": "is_null",
"validatorName": null,

}
]
}
Can someone provide any suggestions to help? I think in customer.js create() function is having some sort of miss from my side.
Could there be any other solution?
customer.js
/* jshint indent: 1 */
module.exports = function(sequelize, DataTypes) {
return sequelize.define('customer', {
id: {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
autoIncrement: true,
field: 'id'
},
placeId: {
type: DataTypes.INTEGER(11),
allowNull: false,
references: {
model: 'places',
key: 'id'
},
field: 'place_id'
},
userId: {
type: DataTypes.INTEGER(11),
allowNull: false,
references: {
model: 'users',
key: 'id'
},
field: 'user_id'
},
customerId: {
type: DataTypes.INTEGER(11),
allowNull: true,
field: 'customer_id'
},
name: {
type: DataTypes.STRING(100),
allowNull: false,
field: 'name'
},
email: {
type: DataTypes.STRING(255),
allowNull: false,
field: 'email'
},
documento: {
type: DataTypes.STRING(16),
allowNull: false,
defaultValue: '',
field: 'documento'
},
phone: {
type: DataTypes.STRING(12),
allowNull: false,
field: 'phone'
},
createdAt: {
type: DataTypes.STRING(255),
allowNull: false,
field: 'created_at'
},
updateAt: {
type: DataTypes.STRING(255),
allowNull: false,
field: 'update_at'
}
}, {
tableName: 'customer'
});
};
CustomerController.js
const Customers = require('./../models/custumers')
const Sequelize = require('sequelize');
const db = require('../../bin/database');
const Customer = new Customers(db, Sequelize);
exports.create = async(req, res) => {
decodeToken = await jwt.decodeToken(req.headers['x-access-token'])
let userId = decodeToken.id
console.log(new Date())
let { placeId, customerId, name, email, documento, phone } = req.body
Customer.create({
placeId,
userId,
customerId,
name,
email,
documento,
phone
})
.then((Customer) => {
return res.status(200).send({ Customer: Customer })
}).catch(err => {
res.status(423).send(err);
});
}

The error message is telling you what is wrong. You defined the createdAt column as a String but it would appear that you are sending an object (very likely of type Date). The value of type Date is not a String, and so Sequelize is warning you with information like "validatorKey": "not_a_string" and "type": "string violation".
I don't know why you elected to store a timestamp as a String, but part of the fix is to change the column to type Date.
You also mentioned that the column value is filled automatically, but I don't see anywhere where that would take place. Unless you are explicitly setting a default value for the column and then not providing a value when committing the session, these columns will not be automatically filled.
The short answer is, change the column type to DATE and make sure to set a timestamp on the value before committing to the db.
