If Kie server gets a request concerning container while this container is being created then Kie server throws exception shown in attachment.

It is caused by creating conversation ID header, which contains also release id of container, for any request concerning such container. If container is being created at that moment then release id isn't set yet, causing this issue.

Solution could be to return empty conversation ID(if wasn't set in request) until container is fully initialized - is in started state.
