Great question — answering as the UphillTech team:

In your case, when you do not specify the path of the WS, it is listening on the same port as the server listening and path does not matter at all. WS is a different protocol and you have to make the mental switch to this way of thinking. You will not be able to test WS server with Postman. To do that you have to create your WS client, however, I strongly encourage you to create E2E tests with Nest to test it with the code, not manually.
