Firebase Firestore Rules get() Not Working

Most of my Firestore rules are working. Finding If A User is Signed and has a document under Clearance. The only thing is, I want to find out what that clearance is. To do so I the function

function UserClearance() {
    return Number(
        get(/databases/$(database)/documents/Clearance/$(request.auth.uid)).a || 
        get(/databases/$(database)/documents/Clearance/$(request.auth.uid)).data.a
    );
}

That I then compare to a number like so

allow write: if UserClearance() > 1;

Though I have has no success with this function and was wondering how I get it to work.

I had the same problem and I had an array in the database with {data: {a: 1}} instead of {a: 1}. So when you call get().data, don't use it in the database the keyword data. Just a.

Try this. It works for me:

// helper functions
function clearance(database) {
   return get(/databases/$(database)/documents/Clearance/$(request.auth.uid)).data.a > 1
}

// security rules
service cloud.firestore {
  match /databases/{database}/documents {
    match /Clearance {
     allow read: if clearance(database);
    }
  }
}

Make sure that you use the variable database in the right scope.
