上传内容时出现 Firebase 存储错误（错误？）

Question

我创建了一个将照片上传到我的存储空间的功能。有时它工作正常，但在几分钟内我收到以下错误：Possible Unhandled Promise Rejection (id: 0):FirebaseStorageError {  "code_": "storage/unauthorized",  "message_": "Firebase Storage: User does not have permission to access 'photos/1d1be05f-b82d-4928-9a8e-002abc0d462e'.",  "name_": "FirebaseError",  "serverResponse_": "{  \"error\": {    \"code\": 403,    \"message\": \"Permission denied. Could not perform this operation\"  }}",}我正在使用 Expo，并使用此函数获取本地 uri（用于创建 blob）：export function urlToBlob(url) {  return new Promise((resolve, reject) => {    var xhr = new XMLHttpRequest();    xhr.onerror = reject;    xhr.onreadystatechange = () => {      if (xhr.readyState === 4) {        resolve(xhr.response);      }    };    xhr.open("GET", url);    xhr.responseType = "blob"; // convert type    xhr.send();  });} 我的存储安全规则如下所示：rules_version = '2';service firebase.storage {  match /b/{bucket}/o {    function isSignedIn() {        return request.auth.uid != null;    }    match /photos/{photo} {            function hasValidSize() {        // Max. photo size = 30MB (For all dimensions)        return request.resource.size < 30 * 1024 * 1024;      }      function isImage() {            return request.resource.contentType.matches("image/.*");            }      allow read;      allow write: if isSignedIn() && isImage() && hasValidSize();    }  }}我认为错误就在这里，因为当我删除 uploadTask.then 时工作正常。// 上传到存储 const uploadTask = storageRef.put(blob);uploadTask.on("state_changed", (taskSnapshot) => {  // Update progress bar  const percent =    (taskSnapshot.bytesTransferred / taskSnapshot.totalBytes) * 100;  setUploadProgress(percent);});// When the image is fully uploaded to the storage...    uploadTask.then(async () => {  // <------------------------- When I delete this...       ...         // Reset upload progress      setUploadProgress(null);    }); // <------------------------- ...and this, all works fine  };有任何想法吗？更新当我更改存储规则（删除 isImage() 条件）时，它也适用于 uploadTask。

我认为这是 Expo 错误，因为我从开发模式转移到生产模式，一切正常！
