我收到了错误

gettingdocuments.com.google.firebase.firestore.FirebaseFirestoreException:PERMISSION_DENIED:权限丢失或不足.

对于else语句中的以下代码

db.collection("users")
        .get()
        .addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
            @Override
            public void onComplete(@NonNull Task<QuerySnapshot> task) {
                 if (task.isSuccessful()) {
                     for (DocumentSnapshot document : task.getResult()) {
                         s(document.getId() + " => " + document.getData());
                     }
                 } else {
                     s("Error getting documents."+ task.getException());
                 }
             }
         });

功能代码：

import * as functions from "firebase-functions";
import * as admin from "firebase-admin";

admin.initializeApp();
const settings = { timestampsInSnapshots: true };
admin.firestore().settings(settings);
