[0.71] Invariant Violation: TurboModuleRegistry.getEnforcing(...): 'RTNCalculator' could not be found

[atar9500]

Description

When following RN documentation to set up a turbo module to a new architecture project, I am receiving the following error:

Invariant Violation: TurboModuleRegistry.getEnforcing(...): 'RTNCalculator' could not be found. Verify that a module by this name is registered in the native binary., js engine: hermes

However, in Xcode my module does appear under react-codegen

Note:

I was able to generate with codegen using generate-codegen-artifacts.js instead of generate-artifacts.js, as it was not found in MyApp/node_modules/react-native/scripts/. Shouldn't it be updated in the documentation?

Steps to reproduce

1. Create a New Architecture project follow these steps.
2. Try to add a turbo module following these steps. In order for an error to appear, make sure NativeCalculator.ts would be:

import type {TurboModule} from 'react-native/Libraries/TurboModule/RCTExport';
import {TurboModuleRegistry} from 'react-native';

export interface Spec extends TurboModule {
  add(a: number, b: number): Promise<number>;
}

export default TurboModuleRegistry.getEnforcing<Spec>(
  'RTNCalculator',
) as Spec | null;

The reason I got that error was simply because I placed the podspec file inside the ios folder instead the RTNCalculator 🤦🏽‍♂️
