FirebaseError: Expected type 'Ec', but it was: an object

### someone explains to me why it is happening

```const querySnapshot = getDocs(collection(getFirestore(), "users"));
querySnapshot.forEach((doc) => {
console.log(`${doc.id} => ${doc.data()}`);
});
```

The only entry point provided is the inline JavaScript snippet using getDocs, collection, and getFirestore. Start by checking the asynchronous result from getDocs against the Firestore documentation and reproduce the reported FirebaseError. Done means the cause is established and the snippet can iterate over the query results without that error.
