I am trying to download a file in PDF format using Laravel DomPDF from the following link: https://github.com/barryvdh/laravel-dompdf. However, when I click the button to generate the PDF, an error 'Call to a member function get_cellmap() on null' appears in the return $pdf->stream($pdfName); part. The following is my generatePDF function:
public function generatePdf(Request $request)
{
$check = UserProfileModel::with('user')->where('user_id', auth()->user()->id)->first();
$assign = UserAssignModel::with('agency', 'job', 'user', 'pic')
->where('peserta_id', $check->user_id)
->first();
$agency = AgencyProfileModel::where('id',$assign->agency_id)->first();
$logbook = LogbookModel::with('task')->where('peserta_id', $assign->peserta_id)->get();
$jobdetail= DB::table('job_has_timeline')->where('job_id',$assign->job_id)->first();
// dd($jobdetail);
$data = [
'check' => $check->user->account->intern_status,
'assign' => $assign,
'agency' => $agency,
'data' => $check,
'logbook' => $logbook,
'jobdetail' => $jobdetail,
];
$pdfName = "Report-" . ucwords(strtolower($agency->name)) . "-" . ucwords(strtolower($check->full_name)) . ".pdf";
$pdf = Pdf::loadView('Users.monev.exportpdf', $data);
return $pdf->stream($pdfName);
}
The following is the picture:
