I am using ML-Agents Release 19 and I’m having some issues trying training my AI with imitiation learning. I do not know what is wrong, everything seems to be right, but when I record, my demo files appears with 1kb and it seems to record nothing. Also, when I press play in the editor with Heuristic Only selected, this appears on console:

Couldn’t connect to trainer on port 5004 using API version 1.5.0. Will perform inference instead.

I’ve made a mistake. Inside my Agent, I used a new void Awake() to enable the new input system controls. This mistake makes the Demo Recorder not record your actions.
