У меня есть требование получать zip-файл с использованием SFTP.После того, как мы должны заархивировать файл как есть, он также обрабатывает файл после распаковки zip-файлов.Ниже приведены коды для основного потока и подпотока.agentDataArchiveChannelAdapter () работает нормально, но для другого канала я получаю ошибку ниже.В чем может быть ошибка, как это можно исправить?Я предположил, что surancebayAgentDemographicFlow () поместит записи в прямой канал и будет следовать процессу, как указано.
