Mongoose buffering timed out when model is in a referenced project

The project:

I made a ShoppingCard project for testing typescript references.

The problem:

When models directly included in main project, MongoDB connection successfully works.

Tested in http://localhost:8080/api-docs/

When I move models out to referenced project I get folowing error:

MongooseError: Operation amounttypes.find() buffering timed out after 10000ms

Please help find why Mongoose not work.

I get following answer in mongoose github issue tracker:

> I'm guessing your separate project has a different copy of the
> Mongoose module, so exporting model() exports a model that's connected
> to the wrong copy of the Mongoose module.
>
> Make shoppingcard-models export schemas instead of models, and instead
> call model() in your main project.
