VS Code does not correctly attach to UNIX domain socket

[Neighborkid01]

I am running my rails server with the command rdbg -n -c --open=vscode -- rails s and it will open VS Code but running the attach configuration will result in the error "Can not find attachable Ruby process." and if I run rdbg --util=list-socks I see nothing even though in the server output it specifies a port to listen on.

$ rdbg -n -c --open=vscode -- rails s
DEBUGGER: Debugger can attach via UNIX domain socket (/var/folders/k4/lsrtl0y55718pst90df0ldzh0000gn/T/com.apple.shortcuts.mac-helper/rdbg-501/rdbg-72212)
Launching: code /Users/executor/Documents/GitHub/VideoConnect/
=> Booting Puma
=> Rails 7.0.7.2 application starting in development
...

If I run rdbg -n -c -O -- rails s, then I see two log lines from the server specifying the UDS port and running rdbg --util=list-socks returns the port as expected. If I open VS Code and try to attach to the debugger again with the default config, I get the same error, but if I manually specify the debugPort to be the one from the console output, it is able to connect correctly and everything works as expected.

I can confirm the same issue existing in my case. Is there any plan for fixing this please? It is annoying to change the debug port with each rails app start to be able to attach debugger. Thank you.

One workaround for this issue is to install this extension.

Then add this at the end of your launch.json file

"inputs": [
    {
      "id": "railsSocketPath",
      "type": "command",
      "command": "shellCommand.execute",
      "args": {
        "command": "bundle exec rdbg --util=list-socks",
        "cwd": "${workspaceFolder}"
      }
    }
  ]

Finally in your rdbg config in launch.json, set debugPort like this:
"debugPort": "${input:railsSocketPath}"

When you launch the debugger you will get a prompt at the top of the screen with all available sockets (usually a single entry) to choose from to attach to your Rails server.
It's not as automated as it could be, but it is much less annoying that having to modify the launch.json file every time you restart your sever.
