Problem
When running Jest tests in my Expo 54 / React Native project, one test suite consistently fails with the following error:
The other tests in the suite run fine (16 passed, 4 failed all with this same error).
Environment
expo: ~54.0.33
jest-expo: ~54.0.0
react-native: 0.81.5
@testing-library/react-native: ^13.3.3
jest: ^29
react: 19.1.0
Node: 20.x, Windows 11
**3. Verified `expo-updates` is not imported anywhere** — confirmed with a project-wide search. Not the cause.
**4. Cleared Metro and Jest cache** (`--clearCache`, deleted `.expo` folder, restarted)
Current `jest.config.js`
