Make NestJs returns 404 when EntityNotFoundError exception is thrown

When using findOrFail() or findOneOrFail() from typeORM, a 500 error is returned if there is no entity (EntityNotFoundError).

To make it returns a 404, use an exception filter as described in https://docs.nestjs.com/exception-filters .

Introduction

Disclaimer: I'm a one-day-old Elixir/Phoenix developer.

In Sonny's training yesterday, we used an Ecto.Changeset to handle user registration (a database-backed operation). This worked perfectly for rendering the intial form and re-rendering the form with validation errors.

This is because our Workshop.RegistrationController is calling Repo.Insert which sets the changeset's :action, whether or not the insertion succeeds. Then Phoenix.HTML's form_for function appropriately sets errors on the form so they can be rendered on the page.
