HTTP Debugging

The StructuredOutput class has a withDebug() method that can be used to debug the request and response. 
$result = (new StructuredOutput)
    ->withDebugPreset('on')
    ->with(
        messages: "Jason is 25 years old",
        responseModel: User:class,
    )
    ->get();
// @doctest id="f615"
It displays detailed information about the request being sent to LLM API and response received from it, including:
  • request headers, URI, method and body,
  • response status, headers, and body.
This is useful for debugging the request and response when you are not getting the expected results.
