Quando tento inserir no terminal 'node api/banco-de-dados/createTable.js' ele exibe: Error: Dialect needs to be explicitly supplied as of v4.0.0

createTable.js abaixo

const TableModel = require('../routes/provider/ProviderModelTable')

TableModel
    .sync()
    .then(() => console.log('tabela criada com sucesso'))
    .catch(console.log)

providermodeltable.js abaixo

const Sequelize = require('sequelize')
const instance = require('../../banco-de-dados')

const column = {

    company: {
        type: Sequelize.STRING,
        allowNull: false
    },
    email: {
        type: Sequelize.STRING,
        allowNull: false
    },
    category: {
        type:Sequelize.ENUM('racao', 'brinquedos'),
        allowNull: false
    }

}

const options ={
    freezeTableName: true,
    tableName: provider,
    timestamps: true,
    createdAt: 'dataCriacao',
    updatedAt: 'dataAtualizacao',
    version: 'versao'
