Expo/React-native AsyncStorage.getItem() resolves to null

I'm developing an app in Expo and am facing a very simple problem.

Inside of my App.js:

AsyncStorage.setItem("test", "testVal").then((res) => {
    AsyncStorage.getItem("test", (value) => {
        console.log("VALUE: " + value);
    });
});

The code above logs VALUE: null, instead of VALUE: test. Any ideas on what could be going wrong?

(Using EXPO Version 3.17.21)

This is getItem signature:

static getItem(key: string, [callback]: ?(error: ?Error, result: ?string) => void): Promise

So the first argument of the callback is error. try:

AsyncStorage.setItem("test", "testVal").then((res) => {
    AsyncStorage.getItem("test", (err, value) => {
        console.log("VALUE: " + value);
    });
})
