Firestore错误“用户文档不存在”

我正在进行一个类似于Linktree的项目,并实现了用于身份验证的Firebase和用于数据库的Firestore。身份验证系统运行正常,用户数据保存在名为的集合中 users 。但是,当我重定向到用户的仪表板时,我看到 undefined 在应该显示数据的区域。

在用户的仪表板代码上,我导入了数据库获取所需的所有内容。

import { db, auth } from "@/lib/firebaseConfig";
import { getDoc, doc } from "firebase/firestore";
import { signOut, onAuthStateChanged } from "firebase/auth";



 useEffect(() => {
    const unsubscribe = onAuthStateChanged(auth, async (user) => {
      if (user) {
        console.log("User authenticated:", user.uid); // Add a log to check user UID
        try {
          const userDocRef = doc(db, "users", user.uid);
          const userDoc = await getDoc(userDocRef);

          if (userDoc.exists()) {
            console.log("User document found:", userDoc.data()); // Log the data
            setUserData(userDoc.data());
          } else {
            console.log("User document does not exist."); // Log for debugging
            alert("User document does not exist.");
          }
        } catch (error) {
          console.error("Error fetching user data:", error);
          alert(
            `Error fetching user data: ${
              error instanceof Error ? error.message : String(error)
            }`
          );
        }
      } else {
        console.log("No user is authenticated. Redirecting to login.");
        router.push("/"); // Redirect to home or login if no user is signed in
      }
    });

    return () => unsubscribe();
  }, [router]);

这是我的 firebaseConfig.ts 文件

import { initializeApp } from "firebase/app";
import { getAuth } from "firebase/auth";
import { getFirestore } from "firebase/firestore";

const firebaseConfig = {
    apiKey: process.env.NEXT_PUBLIC_FIREBASE_API_KEY,
    authDomain: process.env.NEXT_PUBLIC_FIREBASE_AUTH_DOMAIN,
    projectId: process.env.NEXT_PUBLIC_FIREBASE_PROJECT_ID,
    storageBucket: process.env.NEXT_PUBLIC_FIREBASE_STORAGE_BUCKET,
    messagingSenderId: process.env.NEXT_PUBLIC_FIREBASE_MESSAGING_SENDER_ID,
    appId: process.env.NEXT_PUBLIC_FIREBASE_APP_ID,
    measurementId: process.env.NEXT_PUBLIC_FIREBASE_MEASUREMENT_ID,
};

const app = initializeApp(firebaseConfig);
const db = getFirestore(app);
const auth = getAuth(app);

export { db, auth };

这是我最新的消防规则

rules_version = '2';

service cloud.firestore {
  match /databases/{database}/documents {
    match /users/{userId} {
      allow read, write: if true;
    }
  }
}

在那之前

rules_version = '2';

service cloud.firestore {
  match /databases/{database}/documents {
    // Allow read and write access to authenticated users on their own documents in the "users" collection
    match /users/{userId} {
      allow read, write: if request.auth != null && request.auth.uid == userId;
    }
  }
}

我多次尝试更改规则,包括使用实际用户的 uid 代码,但什么都没用。我还咨询了各种人工智能工具,但在这种情况下都没有奏效。
