@cipriancaba Hey,

Can you provide a code snippet?

[jinyang1994]

I have the same problem.

import AsyncStorage from '@react-native-community/async-storage';
import pkg from '../package.json';

const TICKET_NAMESPACE = 'ticket';

async onStateChange(state) {
  // ticket = { list: [], count: 0 }
  const {
    [TICKET_NAMESPACE]: ticket,
  } = state;

  await AsyncStorage.setItem('version', pkg.version);
  await AsyncStorage.setItem(TICKET_NAMESPACE, JSON.stringify(ticket));
},

Update:

Sorry, The value ticket is undefined, so something went error.

[syedamirali14]

it is not yet solved?

[luancurti]

This is caused by JSON.stringify check if the variable ticket is not null or undefined

[krizzu]

This happens on ios if either key or value is null/undefined.

Added checks for those in this mr
