I\'m not very familiar with javascript, and stunning, because i can\'t add new property, to object, that fetched from database using ORM names Sequelize.js.
To avoid
you can use map function. this is worked for me.
db.Sensors .findAll({ where: { nodeid: node.nodeid } }) .map(el => el.get({ plain: true })) .then((rows)=>{ response.json( rows ) });
