Invalid session for assistant V2 node using telegram

I attached a telegram receiver and sender to watson assistant. I don't need multiple sessions so I left unchecked the "multiple sessions" checkbox.
When I send a message from my telegram bot, node-red console tells me "Invalid session" coming from assistant v2 node. Why?
If I check multiple session messages passes from receiver to sender without problems but at every message a new session is created and I don't want this.
