No permission error while using Firebase Database

[linuxing3]

When I using the firestack.database() to get key object from firebase real time database, it shows error Client doesn't have permission to access Desired data.
When I changed the rules in firebase console to no auth for reading, it works fine.
Does the database object need extra token to access database?

Rules on firebase console

{
  "rules": {
    ".read": "auth == null",
    ".write": "auth == null"
  }
}

Testing code

export const db = async(key) => {
    let snap = await firestack.database.ref(key).once('value');
    let str = JSON.stringify(snap.val());
    if (snap) {
        Alert.alert(snap.key);
        return snap.val();
    };
};

This has been updated with the latest source. Can you try it using the branch feature/modules branch?
