ApplicationError：使用App Engine中的Java遠程API將文件發送到Google Cloud Storage時出現10

Question

我正在嘗試使用遠程API將舊的Blob從Blobstore遷移到Could Storage，以避免討厭的超時。 但是，每次關閉GcsOutputChannel時，我GcsOutputChannel ApplicationError: 10的GcsOutputChannel -最終沒有上傳的文件。

我的代碼：

//using the deprecated API to read the BlobStore:
FileService fileService = FileServiceFactory.getFileService();
AppEngineFile blobFile = fileService.getBlobFile(new BlobKey("myBlobKeyReadFromDatastore"));
FileReadChannel readChannel = fileService.openReadChannel(blobFile, false);
InputStream is = Channels.newInputStream(readChannel);

//now using the brand new API to write to the GCS:
GcsService gcsService = GcsServiceFactory.createGcsService();
GcsFilename filename = new GcsFilename("MyBucket", "theNameOfTheFileReadFromDatastore");
GcsFileOptions options = new GcsFileOptions.Builder().mimeType("theMimeTypeReadFromDatastore").build();
GcsOutputChannel writeChannel = gcsService.createOrReplace(filename, options);
OutputStream os = Channels.newOutputStream(writeChannel);

//and some reading -> writing...                
byte[] buff = new byte[1024 * 1024];
int read = 0;
while ((read = is.read(buff)) >= 0){
    os.write(buff, 0, read);
}
writeChannel.close(); //<-- Exception here!
readChannel.close();

即使文件大小小於1KB，也會發生此錯誤。 使用用戶<my-app-id>@appspot.gserviceaccount.com將我的Google Cloud Storage配置為存儲桶的所有者，並在項目中“可以編輯”。 帳單也已啟用（在App Engine和Google Cloud Console中均已啟用）。 我正在使用App Engine SDK 1.8.3。

我不知道該怎么辦。 有任何想法嗎？

這是一個錯誤。 此更改已修復： https : //code.google.com/p/appengine-gcs-client/source/detail? r = 104同步到SVN中的最新版本，應該會消失。
