Firestore权限不足或不足

Question

我收到错误消息：Firebase丢失或权限不足

代码：const demoCollectionRef = this.db.collection（'items'）; 返回demoCollectionRef.add（item）;

我认为此错误是由于angularfire2的.add方法引起的。

Firestore规则：

function isAuthenticated() {
  return request.auth.uid != null;
}

function isAdmin() {
    return request.auth.token.admin == true;
}

allow create: if isAuthenticated();
allow update, delete: if isAdmin(); // .add method checks update rules 
// at the place of checking the create rules, which make it send error.

但是，如果我将更新规则更改为：允许更新，则删除：if isAuthenticated（）; 它工作正常
