SequelizeJS Cannot read property 'getTableName' of undefined - node.js

Question

I am running into an issue where I am trying to associate two models that have a one-to-many relationship. For some reason this query is throwing an error despite referencing the relationship.
Here is my error message:
Unhandled rejection TypeError: Cannot read property 'getTableName' of undefined
at generateJoinQueries (/Users/user/Desktop/Projects/node/project/node_modules/sequelize/lib/dialects/abstract/query-generator.js:1181:43)
This is the route:
appRoutes.route('/settings')
.get(function(req, res, organization){
models.DiscoverySource.findAll({
where: {
organizationId: req.user.organizationId
},
include: [{
model: models.Organization, through: { attributes: ['organizationName', 'admin', 'discoverySource']}
}]
}).then(function(organization, discoverySource){
res.render('pages/app/settings.hbs',{
organization: organization,
discoverySource: discoverySource
});
})
});
DiscoverySource:
module.exports = function(sequelize, DataTypes) {
var DiscoverySource = sequelize.define('discovery_source', {
discoverySourceId: {
type: DataTypes.INTEGER,
field: 'discovery_source_id',
autoIncrement: true,
primaryKey: true
},
discoverySource: {
type: DataTypes.STRING,
field: 'discovery_source_name'
},
organizationId: {
type: DataTypes.TEXT,
field: 'organization_id'
},
},{
freezeTableName: true,
classMethods: {
associate: function(db) {
DiscoverySource.belongsTo(db.Organization, {foreignKey: 'organization_id'});
},
},
});
return DiscoverySource;
}
Organization:
module.exports = function(sequelize, DataTypes) {
var Organization = sequelize.define('organization', {
organizationId: {
type: DataTypes.INTEGER,
field: 'organization_id',
autoIncrement: true,
primaryKey: true
},
organizationName: {
type: DataTypes.STRING,
field: 'organization_name'
},
admin: DataTypes.STRING
},{
freezeTableName: true,
classMethods: {
associate: function(db) {
Organization.hasMany(db.DiscoverySource, {foreignKey: 'organization_id'});
},
}
});
return Organization;
}

It seems, that's a duplicate of Sequelize Association Error Cannot read property 'getTableName' of undefined.
However, you need to rewrite your query to look like:
models.DiscoverySource.findAll({
attributes: ['discoverySource'],
where: {
organizationId: req.user.organizationId
},
include: [{
model: models.Organization,
attributes: ['organizationName', 'admin']
}]
})
According to the Sequelize documentation:
[options.attributes] - A list of the attributes that you want to select, or an object with include and exclude keys.
[options.include[].attributes] - A list of attributes to select from the child model.
[options.include[].through.where] - Filter on the join model for belongsToMany relations.
[options.include[].through.attributes] - A list of attributes to select from the join model for belongsToMany relations.
So, [options.include[].through] can only be used in case of Belongs-To-Many association rather than Belong-To used by you for DiscoverySource and Organization models.
