Php 上载时出现Google云存储错误

我在上载时遇到以下错误：

致命错误：未捕获的Google\Cloud\Core\Exception\NotFoundException:{“错误”：{“错误”：[{“域”：“全局”，“原因”：“未找到”，“消息”：“未找到”}]，“代码”：404，“消息”：“未找到”}}位于/www/Google/vendor/Google/Cloud Core/RequestWrapper.php:257堆栈跟踪：#0/www/Google/vendor/Google/Google/Google/Cloud Core/RequestWrapper.php（162）：Google\Cloud\Core\RequestWrapper->converttoogleexception（Object（GuzzleHttp\Exception\ClientException））#1/www/Google/vendor/Google/Cloud-Core/Upload/MultipartUploader.php（64）：Google\Cloud\Core\RequestWrapper->send（Object（GuzzleHttp\Psr7\Request），Array）#2/www/Google/vendoor/Google/vendour/Cloud/storage/Bucket.php（268）：Google\Cloud\Core\Upload\MultipartUploader->Upload（）#3/www/Google/index.php（20）：Google\Cloud\Storage\Bucket->Upload（Resource id#46）#4{main}在第257行的/www/Google/vendor/Google/Cloud Core/RequestWrapper.php中抛出

如果projectd/bucket/file都存在，那么应该这样做：

使用Google\Cloud\Storage\StorageClient；
$storage=新的StorageClient([
“projectId”=>“YourProjectId”
]);
$bucket=$storage->bucket（'mybucker'）；
$bucket->upload(
fopen（'/test.txt'，r'）
);
mybucker
是打字错误吗？
# Includes the autoloader for libraries installed with composer
require __DIR__ . '/vendor/autoload.php';

# Imports the Google Cloud client library
use Google\Cloud\Storage\StorageClient;

# Your Google Cloud Platform project ID
$projectId = 'projectId ';

$storage = new StorageClient([
    'projectId' => $projectId,
    'keyFilePath' =>'./key.json'
]);

$bucket = $storage->bucket('mybucker');

// Upload a file to the bucket.
$file = fopen('./test.txt', 'r');
