Cannot read property '__model' of undefined

Following the tutorial and using the standard built-in user and authentication models, I am unable to save new or updated users. Specific error:
TypeError: Cannot read property '__model' of undefined

I have tried with both in-memory and a Postgres connected database.

It is worth noting that my common > models directory is empty given I haven't extended the built-in models (yet). The examples extend User as Account.

Should this work as is, or do I need to have .js and .json files in the model directory?
Can you supply a more complete example to download and compare?

Yes, you should extend the models in common/models.

We've been planning on releasing a complete CMS example for reference. It's still the early stages on this project. Thanks.
