Next.js ISR页面Firebase权限不足报错排查

问题现象

Web应用内的ISR页面无法正常渲染，抛出Firebase权限不足报错，但单独测试对应权限时功能完全正常，无法定位问题原因。

当前Firestore安全规则配置

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /blogs/{blog} {
      allow read, get;
      allow write, update, create, delete: if (request.auth.uid == "R3tc0RKCDgX8yhaHS5c0Ej3IXxF3");
    }
    match /forum/{forum} {
      allow read, get;
      allow write, create, update, delete: if (request.auth.uid == "R3tc0RKCDgX8yhaHS5c0Ej3IXxF3");
    }
    match /forum/{forum}/messages/{messages} {
        allow read, get;
      allow write, create, update, delete: if (request.auth.uid != null);
    }
    match /chats/{room} {
        allow write, read, get, create, update, delete: if request.auth.uid == get(/databases/$(database)/documents/chats/$(room)).data.uid[0] || request.auth.uid == get(/databases/$(database)/documents/chats/$(room)).data.uid[1];
    }
    match /chats/{room}/messages/{messages} {
        allow write, read, get, create, update, delete: if request.auth.uid == get(/databases/$(database)/documents/chats/$(room)).data.uid[0] || request.auth.uid == get(/databases/$(database)/documents/chats/$(room)).data.uid[1];
    }
  }
}

问题页getStaticPaths实现代码

export async function getStaticPaths() {
  let array = [];

  await getDocs(collection(firestore, "forum")).then((res) => {
    array = res.docs.map((data) => {
      const { id } = data.data();

      return {
        params: { question: id },
      };
    });
  });

  return {
    paths: array,
    fallback: "blocking",
  };
}
