Я столкнулся с проблемой, связанной с концентраторами событий Azure для Kafka.

У меня есть потребитель Кафки, обрабатывающий тему сообщения с именем «ABC», которая имеет следующую конфигурацию:

Потребитель может подписаться на тему «ABC» , но это не удается с приведенной ниже ошибкой:

«Не удалось присоединиться к группе с помощью org.apache.кафка.обычное дело.Исключение KafkaException: Неожиданная ошибка в ответе группы присоединения: Время ожидания запроса истекло.»
