Jest Mocks Always Returning Undefined

[bj97301]

What happened?

i am using async storage and attempting to write some test. I setup the mocks:

  jest.mock('@react-native-async-storage/async-storage', () =>
    require('@react-native-async-storage/async-storage/jest/async-storage-mock'),
  )

but when i try to set then get an item i always get undefined:

 describe(loadSettingsFromLocalStorage.name, () => {
    it('can load settings from local storage', async () => {
      let responseFromSet = AsyncStorage.setItem('settings', 'test')
      console.log(responseFromSet) // undefined
      let responseFromGet = AsyncStorage.getItem('settings')
      console.log(responseFromGet) // undefined

Version
