Expected dynamic type string', but had typeint64 react native

Question

I have this line in my react native app to stock a variable in AsyncStorage:

AsyncStorage.setItem('userId',theuser.id);

but when I run the app it gives me an error:

TypeError: expected dynamic type string', but had typeint64 react native

It works fine when the variable I want to pass is string but I can't pass any object or int variable?

@AndrewLi it has nothing to do with the type of the id I want pass the age for example but It won't It accepts only string — Gregor Samsa

What do you mean it has nothing to do with type? The problem is the type -- the value must be a string. — Andrew Li

@AndrewLi it has nothing to do with the type of the ID, even this "AsyncStorage.setItem('number',15);" will get the same error. — Gregor Samsa

It has all to do with the type! In your counterexample, the second argument is still a number! It can't be a number! That's what the error is saying! — Andrew Li

In the comments above you said you would want to pass a whole object, you would do it like this:

AsyncStorage.setItem('userId', JSON.stringify(theuser));

but then it gives me this error ( JSON Parse error: Unexpected EOF ) when I try to use the field userId.id or userId.department in the app.

How are you parsing it? Here's an example of what to do: AsyncStorage.getItem('userId', (err, user) => this.setState({ user: JSON.parse(user) }));
