Interactive learning not working. (TypeError)

When I run the following command:

python -m rasa_core.train \
     interactive -o models/dialogue \
     -d domain.yml -c policy_config.yml \
     -s data/stories.md \
     --nlu models/current/nlu \
     --endpoints endpoints.yml

I get the following error:

TypeError: type object argument after ** must be a mapping, not NoneType

What do you think is the problem and how do I solve it?

Ehy @seldomcoder. Can you share the entire log of the error. I suspect there are some issues with the training data format, but can’t tell for sure without the full log :slight_smile:
