How to handle Websocket using "hono/vercel" running on NodeJS environment.
I am using NextJS 14 App Router with Hono to handle the API routes. I followed the documentation using 'hono/vercel', but it seems that it doesn't support WebSocket. Then, I switched to 'hono/node-server/vercel', but I encountered some problems with the response (I cannot use it). Please help me.
