I have defined a model as
module.exports = function (sequelize, DataTypes) { const MyModel = sequelize.define(\'MyModel\', { data: { type: DataTypes
JSON data types aren't supported for MySQL.
See the docs here http://docs.sequelizejs.com/en/v3/docs/models-definition/#data-types
A work around could be to use text and stringify/parse when querying it
