ERROR [-] (1) wsgi starting up on http://0.0.0.0:9102

When i am running stackstorm on containers , i see this error in st2stream container during a startup 2019-12-29 19:39:18,166 ERROR [-] (1) wsgi starting up on http://0.0.0.0:9102

Excepting this strange line, all seems ok. st2api and st2auth are starting without this strange error.
The question is if it’s something that can be ignored? How can i test st2stream component in order to make sure that it’s working correctly ? There is not enough documentation about that component and its role in the stackstorm, so it’s a little bit difficult to test it :slight_smile:
