Hi, I have this issue when trying to clear the conversation or send message.
Can someone help me with this?
Can you show more of that log @KabaninArtem where it shows the list index out of range above, not sure what code that is that is failing but seems relevant.
Hmmm, now it works. I just delete models folder and re-traine model 
Not sure unless there was something invalid in there or something odd, let me know if you see it happen again.
