[lorenzo-cavazzi]

When starting a session, the session_launchers endpoints is invoked too early when the project id isn't available yet. This prevents it

Actually, I think the component isn't properly taking into account when session is null.

Thanks to @lorenzo for fixing this!

@leafty, could you clarify what you mean by "not well handled"? I see that the buttons displayed are incorrect. Is there anything else we need to address? If so, we should consider handling those issues in a separate PR.

We can open a new issue for this, but the component doesn't handle properly when its props are null-ish values

@leafty That's a fair point. Since we are fixing the component already, I've added a quick solution for handling invalid namespace/slug values.
