Firebase-Tools：模擬器中的firestore：刪除錯誤

Question

我正在嘗試在 firebase 雲 function 中使用 firebase-tools 的遞歸刪除。 我正在用模擬器對此進行測試。

但目前，我並不是很成功。

似乎 CLI 正在使用 Firestore REST API。 模擬器可以用嗎？

我的 function 是這樣的：

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);
}

這是來自模擬器的日志：

i  functions: Beginning execution of "deleteUserData"
>  Delete user data 4AiyOyCnAPSrKhc1Ycf6nVDqLoD2
>  i  You have set FIRESTORE_EMULATOR_HOST=tornado.local:3344, this command will execute against the firestore emulator running at that address.

謝謝你的幫助！

EDIT 1: it seems the REST API should work with the emulator since it's given as example here: 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，當請求是在文檔示例中的v1端點上發出時，它是在v1beta1端點上發出的。

編輯 2：按照@sam 的建議，我使用非限制性規則進行了測試，並且可以正常工作。 但據我所知，雲功能應該忽略規則（#gangsta）

這是我的“正常”規則：

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;
    }
  }
}

這是我用於測試的那些：

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