Target [Illuminate\Contracts\Debug\ExceptionHandler] is not instantiable in Laravel 11.

[wanadri]

Hi there,

Currently i having some issue migrating from laravel 10 to laravel 11. It prompt an error Target [Illuminate\Contracts\Debug\ExceptionHandler] is not instantiable after i run composer command.

---

Scenario

I run composer command like below:
composer dump-autoload

An error has prompt like a screenshot below:

Since the error it is too general and not show which file causing the error. I try to trace by dd in HandleExceptions class in Illuminate\Foundation\Bootstrap.
Example like below:

public function handleException(Throwable $e)
    {
        dd($e->getTrace()); // log here...

        static::$reservedMemory = null;

        try {
            $this->getExceptionHandler()->report($e);
        } catch (Exception) {
            $exceptionHandlerFailed = true;
        }

An it shows like screenshot below:

and then i saw CollisionServiceProvider class line 61 has been mentioned on the list.
It shows like the screenshot below:

After that, i commented on that part.

And then, i run again the composer command composer dump-autoload.

No error prompt.

maybe too late but if you are using the new boostraping way you need to include ->withExceptions()

$app = Application::configure(basePath: dirname(__DIR__))
    ->withProviders([
    ])
    ->withExceptions() // this
    ->create();
