@anshal as per my experience, I did not see Rasa X 0.42.x (shared linked) successful running with ROS on the other hand, Rasa X 0.39.3 is working fine but I’m not sure it’s compatible with Rasa 3. X or not. So, for installing rasa x 1.X I can’t help you but for Rasa X 0.39.3 + Rasa 2.x contact me.
I’m not sure that I can give you zoom or skype meeting time this week or weekend as me traveling this week. I hope you understand. Thanks.
