Я обновил приложение Rails с 5.1.4 до 5.2.1, и Action Cable работал нормально, но не работает с момента обновления.Кажется, что Websocket работает правильно, но Channel не начинает передачу и потоковую передачу.
У моего сервера разработки нет проблем, поскольку он работал с Rails 5.1.4, а пустое приложение с Rails 5.2.1 работало правильно, включая кабель действий.на моем сервере разработки.
Я понятия не имею, почему канал не запускается.
Журнал работал нормально с Rails 5.1.4.
