UnhandledPromiseRejectionWarning: TypeError: Model is not a constructor

[k-m-a-c]

Hi!

Love the factory-bot Ruby gem, and recently discovered this package when working on a new Node project.

I'm trying to get my first factory set up and am encountering the following error when trying to build model instances:

(node:87398) UnhandledPromiseRejectionWarning: TypeError: Model is not a constructor

(node:87398) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)

The project is using Sequelize and a Postgres database.

The initial factory definition is as follows:

const { factory, SequelizeAdapter } = require('factory-girl');
const Transaction = require('../../models/transaction');

const adapter = new SequelizeAdapter();

factory.setAdapter(adapter);

factory.define('Transaction', Transaction, {
 amount: 10.00,
 currency: 'CAD',
 name: 'Test Subscription Name',
};

Any ideas?
