PERMISSION_DENIED Firestore CloudFunction TypeScript

I have set my Firestore permission so that anyone with my database reference will be able to read or write to my database.

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

我仍然得到

Error: 7 PERMISSION_DENIED: Missing or insufficient permissions.

执行简单的云函数时

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
admin.initializeApp();

export const sendmsg = functions.https.onRequest((request, response) => {
admin.firestore().doc('message/abcd').get()    
.then(writeResult => { 
  console.log("data: "+ writeResult.data());
  const data = writeResult.data()
  response.send(data)
})
.catch(error =>{
  console.log(error)
  response.send(500).send(error)})

});

请帮忙，不确定我做错了什么。谢谢。

使用之前运行过一些云功能的旧项目时遇到了同样的问题。创建了一个新项目，再次部署它，它起作用了。
