I have a project that has an Apollo GraphQL server as well as a Websocket server from Bun. Am I able to run both in the same instance? I'm currently having trouble with the ports.

ws.server = Bun.serve({
...

makes use of the PORT environment variable provided by the runtime but so does the Apollo GraphQL server.

Is there a way for me to specify different ports assigned from Railway? Is that good practice or should they be separate services?
