google-cloud-platform - Google Cloud Function 抛出 404 错误

Question

我创建了一个 Cloud Function，它被设置为由 Google Cloud Storage 存储桶上的 Finalize/Create 事件触发。

我将 10k 图像转储到存储桶中，大部分图像成功运行了 Cloud Function，而有些图像抛出了以下异常，我只是对导致此错误的原因感到困惑。

错误返回 404，但当我检查存储桶时，图像在那里。有没有人有修复以下异常的经验？

出于某种原因，Cloud Function 正在检查一个不存在的目录。

它应该检查以下目录:

https://storage.googleapis.com/download/storage/v1/b/hidden-name/images%2F3683740a95fa3600d4d9a220c9e0b472.jpg

但是，它正在检查以下目录，该目录不存在(/o 文件夹不存在):

https://storage.googleapis.com/download/storage/v1/b/hidden-name/o/images%2F3683740a95fa3600d4d9a220c9e0b472.jpg

这是我遇到的异常:

云函数入口方法:

def for_each_new_image(event, context):   
    blob_name = event['name'].lower()
    bucket_name = event['bucket']   
    create_thumb_move_to_thumbs_bucket(bucket_name,blob_name)

抛出错误的方法:

def create_thumb_move_to_thumbs_bucket(bucket_name,blob_name):     
    bucket = _storage_client.get_bucket(bucket_name)
    blob_in_bucket = bucket.blob(blob_name)

    blob_name = blob_name.replace("ugc_images/","")    
    thumbnail_filename = blob_name.replace(".","-sm.")

    thumbnail_tmp_filepath = '/tmp/{}'.format(thumbnail_filename)       
    download_tmp_filepath = '/tmp/{}'.format(blob_name)    

    blob_in_bucket.download_to_filename(download_tmp_filepath)

抛出错误的行:

blob_in_bucket.download_to_filename(download_tmp_filepath)

我遇到了同样的错误。我试图访问存储桶中不存在的文件。
