This is likely to be your Firestore rules. If it's like this:

rules_version = '2';

      allow read, write: if request.auth.uid != null;
    }
  }
}

then you'll have t be authenticated to grab the data. You can test this quickly (but not permanently) by allowing access to the DB from anyone ...

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if true;
    }
  }
}

... but please do change it to something more secure afterwards.
