How to correcly use Exceptions::dontTruncateRequestExceptions() ?

[sanfair]

I have a hard time understanding how to make it work properly.

Quote from docs:

By default, RequestException messages are truncated to 120 characters when logged or reported. To customize or disable this behavior, you may utilize the truncateRequestExceptionsAt and dontTruncateRequestExceptions methods when configuring your application's exception handling behavior in your bootstrap/app.php file:

bootstrap/app.php

<?php

declare(strict_types=1);

use Illuminate\Foundation\Application;
use Illuminate\Foundation\Configuration\Exceptions;

return Application::configure(basePath: dirname(__DIR__))
  ->withExceptions(static function (Exceptions $exceptions): void {
      $exceptions->dontTruncateRequestExceptions();
  })->create();

routes/web.php

<?php

declare(strict_types=1);

\Illuminate\Support\Facades\Route::get('/test', static function () {
  \Illuminate\Support\Facades\Http::baseUrl('https://google.com')
      ->get('/not-found')
      ->throw()
      ->dump();
});

Result

In the example above, execution will happen in the following order:

1. App bootstrap
2. \Illuminate\Foundation\Configuration\ApplicationBuilder::withExceptions() which stores a callable that will be executed after resolving \Illuminate\Foundation\Exceptions\Handler
3. Route execution
4. Request to 3rd party API
5. \Illuminate\Http\Client\Response::throw()
6. \Illuminate\Http\Client\Response::toException()
7. \Illuminate\Http\Client\RequestException::prepareMessage() <--- truncates response body
8. \Illuminate\Foundation\Exceptions\Handler::__construct()
9. afterResolving callbacks for \Illuminate\Foundation\Exceptions\Handler (callable passed to ApplicationBuilder::withExceptions())
10. \Illuminate\Foundation\Configuration\Exceptions::dontTruncateRequestExceptions() <--- configuration for RequestException to not truncate response body

What is the point of that configuration if that call will happen only after the response has already been truncated?

Am I missing how to use it correctly?
