Error 400 - Code 10005 - Session state wrong: closed

Hey guys ! I'm still having a problem with streaming avatar API. I'm trying to integrate it with OpenAI Assistant in n8n.com, so when I make the http request for starting a new session (I've made the request for get session id, sdp type and sdp data) the output returns it: 400 - "{"code":10005,"message":"session state wrong: closed"}" How can i solve it?
