值得仔细查看您的Firestore规则：

> 基本规则包括一个匹配语句，指定文档路径，以及一个允许表达式，详细说明何时允许读取指定的数据：

service cloud.firestore {
match /databases/{database}/documents {
// 匹配 'cities' 集合中的任何文档
match /cities/{city} {
allow read: if <condition>;
allow write: if <condition>;
}
}
}

您的错误指向这个注意：

> 您只能访问安全规则明确允许您访问的文档。

例如，在@Alex Mamo提到的问题中，解决方案如下：

service firebase.storage {
match /b/{bucket}/o {
match /{userId} {
match /{allPaths=**}{
allow read, write: if request.auth.uid == userId;
} 
}
}
}
英文:

It is well worth to take a look into your Firestore rules:

> Basic rules consist of a match statement specifying a document path and an allow expression detailing when reading the specified data is allowed:

service cloud.firestore {
match /databases/{database}/documents {
// Match any document in the &#39;cities&#39; collection
match /cities/{city} {
allow read: if &lt;condition&gt;;
allow write: if &lt;condition&gt;;
}
}
}

Your error points to this Note:

>You can only access documents that your security rules specifically allow you to access.

For instance: in the question mentioned by @Alex Mamo, the solution was:

service firebase.storage {
match /b/{bucket}/o {
match /{userId} {
match /{allPaths=**}{
allow read, write: if request.auth.uid == userId;
} 
}
}
}

为Kotlin，在Firebase存储中进行规则更改，并替换带引号标记的部分...
允许读取、写入："如果请求授权不为空;"

英文:

for kotlin,
go rules on firebase storage and change with place that marked with quotes
... allow read, write: &quot;if request.auth!=null;&quot;
