Minimal repro: setUpdateRequestHeadersOverride throws InvalidRequestHeadersOverrideException when requestHeaders not in app.config

gistfile0.txt

// app.config.ts
// Minimal reproduction: no requestHeaders declared under updates

export default {
  expo: {
    name: 'repro',
    slug: 'repro',
    version: '1.0.0',
    runtimeVersion: { policy: 'appVersion' },
    updates: {
      url: 'https://u.expo.dev/<your-project-id>',
      // requestHeaders intentionally absent — this causes the bug
    },
  },
};
