Laravel Image Intervention bug - php

Question

I'm trying to use Image Intervention with laravel to resize images.
my code :
<?php
namespace App\Http\Controllers;
use App\Ad;
use App\Categorie;
use App\Http\Requests\AdsRequest;
use App\Mail\RejectedAd;
use App\Mail\ValidatedAd;
use Carbon\Carbon;
use Exception;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Log;
use Illuminate\Support\Facades\Mail;
use Illuminate\Support\Facades\Storage;
use Intervention\Image\Facades\Image;
class AdController extends Controller
{
/**
* AdController constructor.
*/
public function __construct()
{
$this->middleware('auth', ['except' => ['index', 'show']]);
}
/**
* Store a newly created resource in storage.
*
* #param AdsRequest $request
* #return \Illuminate\Http\Response
*/
public function store(AdsRequest $request)
{
$validated = $request->validated();
$idAuthor = Auth::user()->id;
if (Auth::user()->activite !== 'particulier') {
$pro_ad = true;
} else {
$pro_ad = false;
}
$ad = new Ad();
$ad->title = $validated['title'];
$ad->content = $validated['content'];
$ad->price = $validated['price'];
$ad->zip = $validated['zip'];
$ad->city = $validated['city'];
$ad->categorie_id = $validated['categorie'];
$ad->user_id = $idAuthor;
$ad->publication_date = Carbon::now('Europe/Paris')->addDay(2);
if (isset($validated['descr']) && $validated['descr'] !== null) {
$ad->subcategory = $validated['descr'];
}
$ad->pro = $pro_ad;
$ad->save();
if (isset($validated['tag']) && $validated['tag'] !== null) {
$ad->Tag()->attach($validated['tag']);
}
$ad->save();
if ($request->hasFile('file')) {
Storage::disk('public')->makeDirectory("ad-$ad->id");
foreach ($request->file('file') as $image) {
if ($image) {
// Get filename with the extension
$filenameWithExt = $image->getClientOriginalName();
// Get just filename
$filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);
//Get just extension
$extension = $image->getClientOriginalExtension();
// Filename to store
$filenameToStore = $filename . '_' . time() . '.' . $extension;
// Upload image
$image->storeAs("/public/ad-$ad->id", $filenameToStore);
print_r('resize');
$img = Image::make(storage_path('app/public') . "/ad-$ad->id/" . $filenameToStore)->resize(400, 150, function ($constraint) {
$constraint->aspectRatio();
});
$img->save(storage_path('app/public') . "/ad-$ad->id/" . $filenameToStore);
print_r('resize fin');
$ad->File()->create(['path' => $filenameToStore]);
}
}
}
$ad->save();
return redirect(route('annonces.show', ['id' => $ad->id]));
}
}
but only the first print_r is displayed the rest is as not run.
Thank you in advance for your answers.
