Rasa вылетает при отправке сообщения

Я установил Rasa без ошибок. Когда я запускаю оболочку rasa, сервер запускается, и мне предоставляется приглашение чат-бота. когда я ввожу привет, я получаю следующую ошибку:

Bot loaded. Type a message and press enter (use '/stop' to exit):

У меня не было проблем с установкой, так как я новичок в Rasa, я не уверен, в чем проблема.

Пожалуйста, порекомендуйте. Спасибо
