rasa: Rasa shell error: TypeError: argument of type 'NoneType' is not iterable

Rasa version: 1.3.6

Python version: 3.6.9

Operating system (windows, osx, …): rsa/rasa docker image

Issue: When I’m using the shell and send a message, the following error is displayed. The correct response is displayed after the error but I get the exception.

Error (including full traceback):

Exception occurred in one of response middleware handlers
Traceback (most recent call last):

adding --cors '*' to your arguments should fix it, it does for me

fixing it now

This problem disappears when I use Rasa 1.3.3. Here is exactly what I did to install Rasa 1.3.3:

Created a new virtual environment using virtualenv with python 3.6.5.
Downloaded the Rasa 1.3.3 source code from the official release here.
Followed the installation steps described here.

@teresalazar13, hope this can help

adding --cors ‘*’ definitely Help! 😃

I am also facing the same issue and downgrading is not an option as rasa X will not otherwise.
