Как мне отладить эту трассировку стека? (Google.auth.transport.grpc.AuthMetadataPlugin)

Я создал функцию, которая:

  • запускается каждую минуту через облачный планировщик
  • читает BLOB-объект как строку из хранилища облачного хранилища
  • пишет сообщенияк теме pubsub

Я получаю ошибки соединения примерно в 5% случаев, которые, по-видимому, ссылаются на пакеты сайтов python по сравнению с моим реальным кодом. Как продолжить отладку этой проблемы?

Я добавил повторы на каждом этапе чтения из облачного хранилища, но, похоже, эта ошибка возникает еще до того, как мой код даже начинает работать. Альтернативно, журналы не попадают в стековый драйвер?

Вот полная трассировка стека. Я не вижу, где какая-либо из них ссылается на строки в моем коде.

Я обнаружил, что проблема заключается в blob.download_as_string() получении ошибки подключения.

Обходной путь, который я нашел в этой теме , заключается в добавлении ConnectionResetError и ProtocolError в качестве исключений, которые такжеПовторите попытку. 

from urllib3.exceptions import ProtocolError
from google.api_core import retry

predicate = retry.if_exception_type(
    ConnectionResetError, ProtocolError)
reset_retry = retry.Retry(predicate)

data = reset_retry(blob.download_as_string)()

Хотелось бы знать, почему эта ошибка соединения возникает так часто, и удивляюсь, когда Google исправит ее ...
