Firestore CollectionGroup查询权限被拒问题排查求助

问题背景 #

今年3月在Frank van Puffelen的帮助下，成功配置了Firestore单字段collection-group查询的索引，该查询长期可用。约4周前另一处同类型查询失效，经Doug Stevenson指导得知Google调整了collection-group查询配置，按照官方文档修改后恢复正常。但今日原本正常的主查询也失效，按文档调整安全规则后仍无济于事。

Flutter 代码实现 #

void signUserIn() async {
      try {
        // try sign-in
        await _auth.signInWithEmailAndPassword(
            email: emailControl.text.trim(),
            password: passwordControl.text.trim());

        // if sign-in succeeds: confirm user's registered-date
        if (_auth != null) {
          await _dB
              .collectionGroup('signInData')
              .where('firebaseUserID', isEqualTo: _auth.currentUser!.uid)
              .get()
              .then((QuerySnapshot querySnapshot) {
            querySnapshot.docs.forEach((doc) {
              registeredDate = doc['registeredDate'];
              print(doc['registeredDate']);
            });
          });
        }

Firestore 索引配置 #

• 索引1：针对collection-group signInData，配置了firebaseUserID（升序）与__name__（升序）的复合索引，状态为已启用
• 索引2：针对collection-group signInData的另一项索引配置，包含firebaseUserID字段

Firestore 安全规则 #

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {

match /{path=**}/signInData/{options1} {
                  allow create;
                    allow read, write, get, update: if request.auth != null;
                } 

       }
}

错误信息 #

W/Firestore(16490): (24.7.0) [Firestore]: Listen for Query(target=Query( collectionGroup=signInData where userID==XXXXXXXXXXXXXXXXXXX order by __name__);limitType=LIMIT_TO_FIRST) failed: Status{code=PERMISSION_DENIED, description=Missing or insufficient permissions., cause=null}

求助内容 #

想了解问题所在，以及Google是否再次更新了collection-group查询配置，恳请协助。
