Migrate functions are not executed

[rroehrig]

I'm struggling for a while but cannot figure out why my code is not working.
The app.version is correctly increased (2 after rehydrate) but the migration functions which are specified in the manifest seem not to be executed.

const configureStore = () => {
  const manifest = {
    1: state => state,
    2: state => /* migrates moduleToBeMigrated */,
  };

  const migration = createMigration(manifest, 'app');

  const store = createStore(
    reducers,
    undefined,
    compose(
      migration,
      autoRehydrate(),
      applyMiddleware(loggerMiddleware, thunkMiddleware),
    ),
  );

  persistStore(store, {
    whitelist: ['moduleToBeMigrated', 'app'],
    storage: AsyncStorage, // It's a react-native app
  });

  return store;
};

Things I tried:

• I wrote a unit test for the migration function -> it's working as expected!
• I've tried to set an initial state with app.version = 0 and 1.
• I've added a dummy reducer app with and without initial version number.
• I've added console.log's but they are not printed
• I've added breakpoints in the migration function but they are not reached.

My versions:
redux-persist-migrate@4.1.0
redux-persist@4.8.2
redux@3.7.1

Any ideas? Anything wrong with my code? Thanks in advance!

Fixed for me after upgrading to 5.0.0
