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.
