I noticed that graph.yaml is not enough for audio-graph. Because audio-graph needs extra propaties for endpoint, and your endpoint is defined under port. Maybe can't add additonal propaties (?) for it ? Maybe we can, but I'm not expert of Json-Schema. It is very difficult for me to create even *standard* ones. I will continue current style to avoid unknown error (It always indicates me unknown error :() Thank you for your help !! Best regards --- Kuninori Morimoto
