zun and zun-ui built from source stable/train running on centos7 and using python-zunclient 3.6.0. When I start an interactive container with heat os::zun:container. I am unable to see anything in the console through zun-ui. It seems like the socket is open, but it returns nothing. I can type commands and they appear in the logs, but do not show/render in the console window. If I attach to that same container with cli I have no issues getting an interactive shell and using it. I could not find much in the logs, but with debug on for zun-wsproxy I get the following.
