Firestore安全问题，权限错误

Question

我的聊天记录显示缺少权限或权限不足，无法阅读我的聊天应用程序中的消息。聊天是邀请集合的子代，它的消息带有以下界面：

界面：

export interface Bericht {
    sender_uid: string;
    sender_name: string;
    receiver_uid: string;
    receiver_name: string;
    date: string;
    timestamp: any;
    message: string;
    read: boolean;
    invite_id: string;
    message_id: string;
    }

Firestore规则：

service cloud.firestore {
  match /databases/{database}/documents {

     match /invites/{invite_id} {
     allow list: if isSignedIn();
        allow delete: if isOwner(existingData().sender_uid) || isOwner(existingData().receiver_uid);
      allow create, update: if isOwner(incomingData().sender_uid) || isOwner(incomingData().receiver_uid);

    match /chat/{message_id} {
        this line needs a fix ---> allow read: if isOwner(existingData().sender_uid) || isOwner(existingData().receiver_uid) || isOwner(incomingData().receiver_uid) || isOwner(incomingData().receiver_uid);// <---- this line needs a fix
      allow create, update: if isOwner(incomingData().sender_uid) || isOwner(incomingData().receiver_uid);
    }


    }


    // auth function
    function isOwner(uid) {
    return request.auth.uid == uid;
    }

    // data functions
    function existingData() {
    return resource.data;
    }
    function incomingData() {
    return request.resource.data;
    }
  }
}
