  "configurations": [
    {
      "name": "Listen for Xdebug",
      "type": "php",
      "request": "launch",
      "port": 9000,
      "hostname": "localhost",
      "pathMappings": {
        "/app/config": "${workspaceFolder}/config",
        "/app/web/sites/default/files": "${workspaceFolder}/files",
        "/app/web/themes/custom/custom": "${workspaceFolder}/themes/custom"
      }
      // "stopOnEntry": true,
      // "log": true,
    }
  ]
}

4. In the Run tab of Visual Studio Code, click the green arrow next to “Listen for Xdebug”.
5. Enable Chrome Xdebug plugin on the listening page
6. Load a webpage or run a Drush command
