Google drive API is giving 500 internal server error

Question

I have tried below code to download files from google drive

String fileId = "0BwwA4oUTeiV1UVNwOHItT0xfa2M";
OutputStream outputStream = new ByteArrayOutputStream();
driveService.files().get(fileId)
    .executeMediaAndDownloadTo(outputStream);

Some files are getting downloaded few files are not getting downloaded(It was working few days back). I am getting this error.

Caused by: com.google.api.client.http.HttpResponseException: 500 Internal Server Error

 }
}
