Encoding error when running Rasa X

Hey all,

I decided to migrate my routines and data to the new version of Rasa (2.1.3).

I trained NLU using my previous json dataset with success: rasa shell nlu works smoothly.

I trained rasa and calling my bot using rasa shell command works just fine.

Problem happens when I call rasa x, having the following output:

Starting Rasa X in local mode... 🚀

Sorry, something went wrong (see error above). Make sure to start Rasa X with valid data and valid domain and config files. Please, also check any warnings that popped up.

I wonder if this has something to do with some slot values on my stories after converting the file presenting special characters as ‘ç’, ‘á’ and etc… But Rasa X was working finely before the major upgrade.

Any hints on what can I do to fix this?

A thing worth mentioning: I am using Windows 10 for this.

same problem!
