Не удалось выполнить попытку блокирования соединения pika (версия 1.0.0 pika). Исключение, показанное в журнале приложения - adapters.utils.connection_workflow.AMQPConnectorStackTimeout - не похоже ни на одно из исключений в pika.exceptions.
Разве pika не должна преобразовывать внутренние исключения, подобные этим, в одно из тех, что есть в pika.exceptions, перед тем как отобразить его вызывающей стороне?
Если нет, то как мне перечислить все возможные исключения, которые может сгенерировать pika, чтобы я мог решить, с чем может обращаться вызывающий объект, а с другим - нет? (По сути, вызывающий должен решить, следует ли выйти из невосстановимого исключения или повторить попытку, если условие, вероятно, является временным.)
Возможно, я неправильно истолковал журнал приложения, который выглядит следующим образом:
