1. ScoresController不会产生错误
2. rasa data validate不会产生错误
3. rasa train开始行动
4. rasa run actions -vv运行助手

问题

当我运行启用身份验证的意图时，在rasa shell -vv中出现
• 错误
  • shell
  • asyncio - Task exception was never retrieved future: <Task finished coro=<configure_app.<locals>.run_cmdline_io() done, defined at c:\app\miniconda2\envs\my_ens\lib\site-packages\rasa\core\run.py:124> exception=TimeoutError()>
  • asyncio - Task exception was never retrieved future: <Task finished coro=<RestInput.on_message_wrapper() done, defined at c:\app\miniconda2\envs\my_envs\lib\site-packages\rasa\core\channels\channel.py:392> exception=AttributeError("'dict' object has no attribute 'split'") created at c:\app\miniconda2\envs\my_envs\lib\site-packages\rasa\core\channels\channel.py:432>
• 该操作可以完美运行并从REST API中获取api_token

问题

当操作检索身份验证令牌并将其发送回Rasa时，为什么会出现这些错误？

文件：actions.py

AttributeError: 'dict' object has no attribute 'split'
