Error: Failed to open PDF file: 
   https://tax-ein-number.com/pdf/fss4.pdf
Errors encountered.  No output created.
Done.  Input errors, so no output created.

Here is the Laravel Controller code

use mikehaertl\pdftk\Pdf;
class FillAblePdfController extends Controller
{
    public function autofillpdf_ss4(Request $request, $order_id)
    {
         $filename = 'pdf_'.rand(2000, 1200000).'.pdf';
         $pdf = new Pdf(asset('/pdf/fss4.pdf'),[
                    'command' => public_path('/pdftk/bin/pdftk'),
                    'procEnv' => ['LD_LIBRARY_PATH' => public_path('pdftk/bin/libgcj.so.10')]
         ]);
         $result = $pdf->fillForm([
                'topmostSubform[0].Page1[0].f1_40[0]' => 'Jhon',
         ])->needAppearances()->saveAs(asset('pdf/'.$filename));

         if ($result === false) {
            echo $pdf->getError();
        }  
    }
}

One important thing I have this code also tested in Core PHP (without Laravel Framework) on the same hosting and domain that is working fine but i need it in Laravel.

Core PHP code that works as I need

require_once 'vendor/autoload.php';
use mikehaertl\pdftk\Pdf;
$filename = 'pdf_'.rand(2000, 1200000).'.pdf';
$pdf = new Pdf('./fss4.pdf',['command' => './pdftk/bin/pdftk','procEnv' => ['LD_LIBRARY_PATH' => './pdftk/lib/libgcj.so.10']]);
$result = $pdf->fillForm([
        'topmostSubform[0].Page1[0].f1_40[0]' => 'Ali'
    ])->needAppearances()
    ->saveAs('./pdf/'.$filename);
if ($result === false) {           
  echo $pdf->getError();
}
echo 'Your PDF is now generated, <a href="./pdf/'.$filename.'" download>Download it here</a>';
