I use Core: 0.14.4, nlu : 0.13.1, and set up channel via Slack but have below errors. Any one can help me?

Hey @tuanvuvo, if you updated your core to 0.14.4, you should also update your nlu to 0.15.0, since the new core is not compatible with the old NLU. Looks like you’re using docker, which images are you using (along with your sdk version?))

Okie for me now when use 1.0. Thanks for your comments @erohmensing

Okay, let me know if you have any issues setting it up in rasa 1.0 :slight_smile:
