Debbugger su OPTA

Hello everyone,
I would like to use debugging on OPTA but prior configuration is required

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  "version": "0.2.0",
  "configurations": [
  ? ? ? ? ? ? ?
  ]
}

Where can I find useful information to solve the problem?
Thank you
