React Native AsyncStorage not getting data

Question

I am using following code for storing and retrieving data. But it isn't working as I want.

Setting data:

async setDataFromApi(token, json) {
const {goBack} = this.props.navigation; // Navigation
let iext_inf = {
  token: token,
  userid: json.data.id,
  username: json.data.username,
  image: json.data.profile_picture,
};
console.log(iext_inf);
try {
  await AsyncStorage.setItem('iext_inf', JSON.stringify(iext_inf) ); // Stuck here
  goBack();
} catch (error) {
  console.log("Error");
}
}

Getting data:

async componentWillMount() {
    try {
      const value = await AsyncStorage.getItem("iext_inf"); //Stuck here
console.log(value);

  if (value !== null){
    this.setState({
      data : value
    })
  }

  if ( this.state.data !== null ) {
    this.props.navigation.navigate('Home', {'access_token': value});
  }

} catch (error) {
  console.log(error);
}
}

What am I doing wrong? I tried adding single data and retrieving it and it worked for some reason. Now it's not. Thank you in advance.

is the data that you are passing to the asyncstorage valid? are you getting any error — Panagiotis Vrs

can you try callbacks like AsyncStorage.getItem('iext_inf', (err, result) => { }) — Panagiotis Vrs

@PanagiotisVrs Tried it already. Not getting any error or result! — Shihab

can i suggest try a static object like the example of react native ? let UID123_object = { name: 'Chris', age: 30, traits: {hair: 'brown', eyes: 'brown'}, }; — Panagiotis Vrs

AsyncStorage only takes string as a value and key.

You are passing an object try to set string not an object. I am not sure JSON.stringfy() works for AsyncStorage.

this is not valid. JSON.stringify turns the object to a string. There is no reason why this is not working for the AsyncStorage

The value that I was passing was null which caused AsyncStorage to stuck without throwing any errors.
