Question

运行Rasa时（我写了一个简单的模型来识别有人告诉我他的名字，并将该名字存储在数据库中），但是每次运行Rasa时，都会遇到Rasa的core.py抛出的异常：

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

TypeError: argument of type 'NoneType' is not iterable

我尝试在调试中运行，但是似乎没有消息与该问题有关。有什么建议吗？

事实证明，这是v1.3.7（和v1.3.8）中的Rasa错误。我发现有两种解决方法：

降级至v1.3.3：pip uninstall rasa; pip install rasa==1.3.3 运行
使用参数cors '*'运行rasa
