Trying to run xDebug over Docker, I mapped 9003 to 9003 using Docker-Traefik and I am running my php application over WSL2, so I am wondering what I am doing wrong.

Here are my xDebug configs on Visual Studio:

    "configurations": [
        {

            "type": "php",
            "request": "launch",
            "port": 9003,
            "runtimeExecutable": "C:\xampp\php\php.exe"
        },
        {
            "name": "Launch currently open script",
            "type": "php",
            "request": "launch",
            "program": "${file}",
            "cwd": "${fileDirname}",
            "port": 9003,

        }


    ]
}
