iOS error while trying to write fetched database data using AsyncStorage when App is in Background

This is the context :

When I open my app I'm querying my firebase database. These queries are async, I'm waiting for firebase to give me the answer and then I return the value in redux. I'm using redux-persist so when redux get the response of firebase, redux-persist write the data on my phone.

This is the problem :

The problem is that if the user leave the app and then reopen it, if firebase return the response while the app is in background, redux-persist will try to write with AsynStorage. iOS doesn't allow this so my app will crash with these 2 errors

 Error storing data for key: "profile"

What I tried :

I have tested two solutions :

First Try I have tried to pause the persistor of redux-persist depending on the app state.

Store.js

export const persistor = persistStore(store, { storage: AsyncStorage }, () => {
    console.log('restored');
});

And then in my Home component

componentDidMount() {
    if (Platform.OS === 'ios') {
        AppState.addEventListener('change', this.handleAppStateChange);
}

handleAppStateChange = (appState) => {
    if (appState !== 'active') {
        persistor.pause();
    } else {
        persistor.resume()
    }
};

componentWillUnmount() {
    if (Platform.OS === 'ios') {
        AppState.removeEventListener('change', this.handleAppStateChange);
    }
}

Result Same Error as before, when I tried to console log the current state of the persistor he was paused and resumed on time.

Second Try I have tried to use a CustomAsyncStorage instead of AsyncStore in the persitStore(), I took all the code from AsyncStorage.js and then I add on every method a verification of the current app State who return the method if app state isn't active.

Result No luck redux-persist and redux stop working.

My Other ideas

• Cancel every call of firebase when the app pass in background -> Can't be done no Method exist for that

• In each method where I call Firebase and dispatching value in redux, check the current state of the app and return it only if app is active -> That means I should check every call so it's a lot of repetition.

React-native Version: 0.39.2

Redux-persist Version: 4.4.2

I'm open of any idea or any help for this case, what do you think I should do for resolve this issue? And which is the best

Thanks.
