Reload containers:

make reload ENV=prod

# 👉 same as: docker compose up -d 

Go to your local "g3w-admin" repository and attach the debugger:

# g3w-admin/.vscode/launch.json
{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "G3W Gunicorn: Attach",
      "type": "debugpy",
      "request": "attach",
      "connect": {
        "host": "localhost",
        "port": 5678
      },
      "pathMappings": [
        {
          "localRoot": "${workspaceFolder}/g3w-admin",
          "remoteRoot": "/code/g3w-admin"
        }
      ],
