Please help me out with it. New here & wants to try my NLU model to serve as API using docker. Any help is appreciated. Thank you for your time.

Even tried using this command sudo docker run \ -v $(pwd)/models:/app/models \ rasa/rasa:latest-full \ run --enable-api -m models/20190930-103430.tar.gz But still it goes into waiting state.

@Akshay23 which version of rasa are you using? And can you try passing the --debug flag as well?

Version of rasa is 1.3.6

Sorry for inconvenience here @akelad. But i got the following command running sudo docker run \ -v $(pwd)/models:/app/models \ rasa/rasa:latest-full \ run --enable-api -m models/20190930-103430.tar.gz All i needed was to find IP of docker.

But still the NoneType error persists. Here i tried using debug but cannot figure out what is happening with the command

sudo docker run -v $(pwd)/models:/app/models rasa/rasa:latest-full  run --enable-api -m models/nlu-20191001-163401.tar.gz --debug

Here is the output of it

@Akshay23 so this is an issue we noticed which can temporarily be fixed by passing --cors "*" as an additional flag. We’re also working on getting a proper fix out

Thank you for updating me here for the same. Will try it and let you know about it.

Edit 1:

Yes it is working as of now. Thank you for your support.
