Problem Description

Just following Native Platform: Native Component (Fabric) I get a runtime error and not a basic, working native component.

The exact error I get is

View config getter callback for component CircleMask must be a function (received undefined)

It's frustrating as a simple first step in realizing a basic native component is hindered. This used to work in 0.80 days.

Steps To Reproduce
  1. Follow Native Platform: Getting Started
  2. Follow Native Platform: Native Modules
  3. Follow Native Platform: Native Components (Fabric)
Expected Results

An app window should show a circle mask component. This isn't the case. Aforementioned runtime error is seen.

CLI version

20.0.0
