I have set up rasa and created a chatbot however when I access rasa x the payload butttons does not work. I tried rasa x --debug but it gives the error:
rasa.core.channels.channel - An exception occured while handling user message ‘None’. if message.text.startswith(INTENT_MESSAGE_PREFIX): AttributeError: ‘NoneType’ object has no attribute 'startswith’
The error is same if I use Rasa Chatroom. If I use rasa shell --debug everything works well without the error.
