My requirement is to reverse proxy requests from the /ws_yk path to the service on port 8091 after removing the _yk suffix. Port 8091 is a Spring Boot application with an endpoint at the /ws path. The current issue is that direct access results in a 404 error. The logs are as follows.
here is my Caddyfile

:443 {
  tls  /data/certs/cert.pem /data/certs/key.pem
  handle_path /api_yk/* {
       reverse_proxy http://127.0.0.1:8091
  }
  handle /ws_yk/*  {
    uri path_regexp ws_yk ws
    reverse_proxy   http://127.0.0.1:8091
  }
  handle_path /oss_yk/*   {
        file_server {
                root /var/lib/rms-yk
        }
 }
  handle_path /api/* {
       reverse_proxy http://127.0.0.1:8090
  }
  handle /ws/* {
       reverse_proxy http://127.0.0.1:8090
  }
  handle_path /oss/*   {
        file_server {
                root /var/lib/rms
        }
 }
 file_server {
        root /var/lib/rms/dist
  }
}

When i send a wss connection request in postman like this wss://192.168.103.30/ws_yk/status I got 404 error

Here is log of caddy when i sent the request:

    }
  },
  "method": "GET",
  "uri": "/ws/status?satoken=8cef785f53224ffebe828c5797163cfc"
}

Any idea?

I hope to access my WS endpoint according to the above requirements.
