Firebase-Tools：模拟器中的firestore：删除错误

Question

我正在尝试在 firebase 云函数中使用 firebase-tools 的递归删除。我正在用模拟器对此进行测试。

但目前，我并不是很成功。

CLI 似乎正在使用 Firestore REST API。模拟器可以用吗？

我的功能是这样的：

import * as firebaseTools from 'firebase-tools';
import { db } from './admin';

const DEBUG = true;

export async function deleteUserData(userId) {
  if (DEBUG) console.log('Delete user data', userId);

  await firebaseTools.firestore.delete(`users/${userId}/contacts/`, {
    project: db._projectId,
    recursive: true,
    yes: true, // auto-confirmation
  });

  if (DEBUG) console.log('User data deleted', userId);
}

这是来自模拟器的日志：

i  functions: Beginning execution of "deleteUserData"

>  i  You have set FIRESTORE_EMULATOR_HOST=tornado.local:3344, this command will execute against the firestore emulator running at that address.

感谢您的帮助！

编辑 1：REST API 似乎应该与模拟器一起使用，因为它在此处作为示例给出：https://firebase.google.com/docs/emulator-suite/connect_and_prototype#clear_your_database_between_tests

我注意到，在我的例子中，请求是在v1beta1 端点上发出的，而它是在文档示例中的v1 端点上发出的。

编辑 2：遵循@sam 的建议，我使用非限制性规则进行了测试，并且可以正常工作。但据我所知，Cloud Functions 应该忽略规则（#gangsta）

这是我的“正常”规则：

service cloud.firestore {
  match /databases/{database}/documents {
    // Make sure the uid of the requesting user matches name of the user
    // document. The wildcard expression {userId} makes the userId variable
    // available in rules.
    match /users/{userId} {
      allow read, update, delete: if request.auth.uid == userId;
      allow create: if request.auth.uid != null;
    }
    match /users/{userId}/{document=**} {
      allow create, read, update, delete: if request.auth.uid == userId;
    }
  }
}

这是我用于测试的那些：

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