Firestore 返回根目录中的所有文档

Question

At the root of my firestore db I have a 'users' and 'accounts' collections. Whenever I try to return all documents in either of those collection I get an error (there is definitely data there):

Uncaught (in promise) FirebaseError: Null value error. for 'list' @ L59, Null value error. for 'list' @ L63, Null value error. for 'list' @ L76

Code to produce above error:

const query = fs.query(
     fs.collection(firestore, 'accounts'),
  );

  const querySnapshot = await getDocs(query);

  querySnapshot.forEach((doc) => {
     console.log(doc.id, ' => ', doc.data());
  });

If I try and return all documents from any sub collection it works fine:

const query = fs.query(
     fs.collection(firestore, `accounts/${accountId}`, 'sites'),
  );

  const querySnapshot = await getDocs(query);

  querySnapshot.forEach((doc) => {
     console.log(doc.id, ' => ', doc.data());
  });

Any ideas why this would be, am I querying wrong? Could it be something to do with firestore rules?

Ta.

Answer 1

In case anyone else has this issue I've found the cause.

I just disabled all rules in firestore.rules (created by someone else) and added a general rule to access all documents if authenticated:

match /{document=**} {
  allow read, write: if request.auth != null;
}

This then stopped the error and listed all documents.
