Doesn't generate field information

I have a model generated by Sequelize with the following information:

module.exports = (sequelize, DataTypes) => {
  const user = sequelize.define('test', {
    firstName: DataTypes.STRING,
    lastName: DataTypes.STRING,
    email: DataTypes.STRING,
    testField: DataTypes.STRING,
    anotherTest: DataTypes.STRING
  }, {});
  user.associate = function(models) {
    // associations can be defined here
  };
  return user;
};

Running makemigration generates the following:

'use strict';

var Sequelize = require('sequelize');

/**
 * Actions summary:
 *
 * createTable "users", deps: []
 *
 **/

var info = {
    "revision": 1,
    "name": "user",
    "created": "2019-10-20T04:47:04.496Z",
    "comment": ""
};

var migrationCommands = [{
    fn: "createTable",
    params: [
        "users",
        {

        },
        {}
    ]
}];

module.exports = {
    pos: 0,
    up: function(queryInterface, Sequelize)
    {
        var index = this.pos;
        return new Promise(function(resolve, reject) {
            function next() {
                if (index < migrationCommands.length)
                {
                    let command = migrationCommands[index];
                    console.log("[#"+index+"] execute: " + command.fn);
                    index++;
                    queryInterface[command.fn].apply(queryInterface, command.params).then(next, reject);
                }
                else
                    resolve();
            }
            next();
        });
    },
    info: info
};

Doesn't look like there is any code related to the fields. Running runmigration confirms this since it only creates the table with no fields in it.

Is it something I'm just doing wrong?

Same problem. Only table generated, no columns.

This is still a problem

if you can check, please check my pull request that fixes this specific issue, it is just that sequelize 5.x changed some attributes

@flexxnn please accept @moda20 's PR, we are stuck in Sequelize 4.x

@moda20 I had an issue with your fix. I changed property path to models and it's worked fine with autogenerated models/index.js

This pull request fix this issue #75
