Php 带有文件输入的表单在GAE上不起作用

嘿，我正在尝试从多部分/表单数据表单中的输入文件上载一个文件。我使用的是symfony5.1。代码在我的本地服务器上运行得很好，但在Google App Engine prod环境中提交表单时返回500错误

这是我的控制器代码：

$advertiserID = $this->getUser()->getAdvertiserId();
    $form = $this->createForm(UploadCreativeFormType::class, null, [
        'advertiserId'=>$advertiserID,
    ]);
    $storage = new StorageClient([
        'keyFilePath' => '../gcloud_auth.json'
    ]);
    $bucket = $storage->bucket('rocketlab-space.appspot.com');
    $form->handleRequest($request);


    if ($form->isSubmitted() && $form->isValid()){
        $data = $form->getData();
        $campaign = $data['campaign'];
        $offerId = $campaign->getOfferId();

        $uploadedFile = $data['creative_url'];
        $newFilename = $offerId.'-'.uniqid().'.'.$uploadedFile->guessExtension();
        $path = $uploadedFile->getPathname();
        $mime = $uploadedFile->getMimeType();

        $bucket->upload(fopen($path, 'r'), [
            'name' => $advertiserID.'/'.$offerId.'/'.$newFilename,
            'contentType' => $mime,

        ]);
        $object = $bucket->object($advertiserID.'/'.$offerId.'/'.$newFilename);
        $response = $object->update(['acl' => []], ['predefinedAcl' => 'PUBLICREAD']);
        dd($response);
    }

    return $this->render('sandbox.html.twig',[
        'uploadForm' => $form->createView()
    ]);

这是我的应用程序。yaml：

runtime: php73

env_variables:
  APP_ENV: prod
  APP_SECRET: *****
  # Add the DATABASE_URL environment variable
  DATABASE_URL: ****
  GOOGLE_STORAGE_BUCKET: "*****"



handlers:
  # Declare the build and bundles directory as static assets to be served by the
  # App Engine CDN.
  - url: /build
    static_dir: public/build
  - url: /bundles
    static_dir: public/bundles

  # Declare any media files in the public directory as static assets as well.
  - url: /(.*\.(ico|txt|gif|png|jpg))$
    static_files: public/\1
    upload: public/.*\.(ico|txt|gif|png|jpg)$

如果我转储表单，它会抛出相同的错误，我甚至无法获取表单对象，因此我猜是关于文件输入或caché目录的问题

任何帮助都将不胜感激！提前谢谢

谢谢！我刚刚为gcloud安装了错误记录器。（正常日志显示了一个500错误，没有更多信息）。盖伊似乎错过了作曲家西蒙尼/默剧。我重新安装了它，它的工作就像一个符咒。

再次感谢

您需要检查开发人员控制台>日志以查看错误说明。我打赌它无法解析这个相对路径：

'keyFilePath'=>“../gcloud\u auth.json'

。将

gcloud\u auth.json

放在应用程序的根目录下（与

app.yaml

目录相同），然后删除

。/
