@akelad I still have on the TODO list to try the --enable-api option with 1.1.4. Doesn’t seem to complain, but i haven’t done a negative test to confirm.
But just upgraded to 1.6.2 and immediately got CORS violation in both chrome and firefox and then setting --cors ‘*’ definitely had an affect and stopped complaining about cors and started working. And in 1.6.2 without the --enable-api
And just to clarify, this is not Rasa X but rather Rasa server (Open Source) and this https and ws communication over websocket channel.
