baseReducer is not a function. (In 'baseReducer(state, action)', 'baseReducer' is undefined)

I am getting this error when I try to setup redux-persist to work with my React Native app. “baseReducer is not a function. (In ‘baseReducer(state, action)’, ‘baseReducer’ is undefined)”

 // configureStore.js
 import { createStore, applyMiddleware, compose } from 'redux';
import { persistStore, persistReducer, autoRehydrate } from 'redux-persist';
import storage from 'redux-persist/lib/storage'; // defaults to localStorage for web and AsyncStorage for react-native
import thunkMiddleware from "redux-thunk";

import rootReducer from './'

const persistConfig = {
  key: 'root',
  storage,
}
const persistedReducer = persistReducer(persistConfig, rootReducer);
const store = createStore(
  persistedReducer,
   {},
   compose(
     applyMiddleware(thunkMiddleware)
   )
 )
 const persistor = persistStore(store)

export default { store, persistor }

 //index.js

const rootReducer = combineReducers({

  search: searchReducer,
  user: userReducer,
  leads: leadsReducer,
  openHouse: openHouseReducer,
  pin: pinReducer,
  houseImage: houseImageReducer,
  switchState: switchReducer
});

export default rootReducer;
