I am using laravel version 9 for doing my project. and there is a feature that needs to let the user export the event ticket. I try to use the package barryvdh/laravel-dompdf . right now I encounter the error of

Call a member function get_cellmap() on null

I tried to read others' posts with a similar issue, but I found out most of them are using the for the view so seems like the solution working for them is not appropriate for me.here is my code :

controller 

 public function GenerateTicket($id)
    {
        $tickets = GiftGivingBeneficiaries::where('gift_giving_id', $id)->get();

        # Retrieve the last batch no. from the gift giving.
        $batch_no = GiftGiving::findOrFail($id)->batch_no;

        GiftGiving::findOrFail($id)->update([
            'last_downloaded_by' => Auth::id(),
            'batch_no' => $batch_no + 1,
        ]);

     
   
       

        $pdf = PDF::loadView('charity.gifts.generate_ticket', compact('tickets'));
        return $pdf->download('event_tickets.pdf');
    }

Not sure if this will help but the way I execute this in my app is like so:

Maybe try storing it first then accessing it? Then delete them after 1 hour?

$pdf = PDF::setOptions(['isHtml5ParserEnabled' => true, 'isRemoteEnabled' => true])->loadView('charity.gifts.generate_ticket', compact('tickets'));
    $pdf->setPaper('a4', 'landscape');
    Storage::disk('reports')->put('tickets'. '.pdf', $pdf->output());
    $url = Storage::disk('reports')->url('tickets'. '.pdf');
