I am having an issue where I am trying to query a subquery by a field, and I have tried the emulator as well as firebase support (still on going, but not solutions yet).

When running the following query:

const queryByNumber = query(
  collectionGroup(this.firestore, 'residents'), 
  where('cellNumber', '==', number)
);
return from(getDocs(queryByNumber)); 

This query has the error of:

Property cellNumber is undefined on object. for 'list' @ L6

This is what the rules look like at the moment

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{path=**}/residents/{residentDoc} {
        allow write: if resource.data.cellNumber == request.auth.token.phone_number;
        allow read: if request.auth.token.phone_number == resource.data.cellNumber;
        //allow read; //temp permission till support fix
      }
      match /Units/{unitNumber} {
        allow read: if request.auth != null;
        function residentDoc(residentId) {
            return get(/databases/$(database)/documents/Units/$(unitNumber)/residents/$(residentId))
        }
        
        match /pets/{petId} {
          allow write: if residentDoc(request.resource.data.residentId).data.cellNumber == request.auth.token.phone_number;
          allow read: if request.auth != null;
        }
      }
    }
}

And this is the firestore data structure at the moment:

I have tried to change my query to have the array-contains in the where clause, but that doesn't change much.

Note: the allow read without the if check allows the data to be retrieved, so the query does work, just the rules to secure it are not`
