Hello guys, In my project I'm trying to convert pdf to jpg and saving in aws (using spatie pdf to image package) so uploading pdf logic is in my controller after 10 mins delay I'm converting pdf to images by processing laravel job. here is my laravel-job logic

public function handle()
    {
        $filePath = 'images/' . $this->request->language . '/' . '_' . $this->request->language;
        $bookPath = $this->book->path;
        $destination_path = Storage::disk('s3')->url($filePath);
        
        $pdf = new Pdf($bookPath);
        $pdf->saveAllPagesAsImages($destination_path);
        return response()->json(['status' => 'True', 'msg' => 'Successfully converted']);
    }

somehow I'm getting Serialization of 'Illuminate\Http\UploadedFile' is not allowed" error. can anyone help me out? Thanks In advance.
