Change your mergePDF function accordingly.

public function mergePDF(){
    $mpdf = new \Mpdf\Mpdf();
    $mpdf->SetImportUse(); //only with mPDF <8.0
    $pagecount1 = $mpdf->SetSourceFile('file1.pdf');
    $tplId1 = $mpdf->importPage($pagecount1);
    $mpdf->useTemplate($tplId1);
    $pagecount2 = $mpdf->SetSourceFile('file2.pdf');
    $tplId2 = $mpdf->importPage($pagecount2);
    $mpdf->useTemplate($tplId2);
    $mpdf->Output();
    }

merge multiple pdf using Mpdf library

merge pdf function

function mergePdf($pdfArr){
    $pdf = new Mpdf();
    foreach($pdfArr as $currentPdf){
      $pagecount = $pdf->SetSourceFile($currentPdf);
      for($i = 1; $i <= $pagecount; $i++){
        $pdf->AddPage();
        $tplId = $pdf->importPage($i);
        $pdf->useTemplate($tplId);
      }
    }
    //direct show on browser
    $pdf->Output();
    
    //spacefic location save file
    $outputpath = 'location/output.pdf';
    $pdf->Output($outputpath, 'F');
}
