我的密码

My code

this.firestore.collection('mycollection').ref
        .orderBy("created","desc")
        .where("field","==",true) 
    <br>

但是当我删除orderby应用时，效果很好

but when i remove orderby app work fine

this.firestore.collection('mycollection').ref 
        .where("field","==",true) 

推荐答案

错误应包含一个链接，您可以单击该链接来创建所述索引.您只需要单击它并等待.

The error shall contain a link on which you can click to create the said index. You just have to click on it and wait.
