i'm facing the same issue. `in stoplight:`  `in swagger:`  but i've read at the [documentation](https://docs.stoplight.io/docs/platform/c2f20944173d7-work-with-media-types#from-the-design-editor) there's works well 🤷‍♂️ confusing right 

I think you can use `io.in(socketId).socketsLeave(['room1',room2'])` instead of `socket.leave()` [#ref](https://socket.io/docs/v4/server-instance/#socketsleave)
