Hello,
We are trying to merge two PDF with PHPDOCX 12.5 :
$merge = new MultiMerge();
$merge->mergePdf([$headerPdf, $clientPdf], $outputPdf);
But we have an error :
Warning: Illegal string offset 'Parent'
$clientPDF has been clean up by pdfcairo
$headerPdf is created by PDPDocx
Both files can be open with Acrobat Reader without error.
We are using PHP 7.4
Thanks
Nicolas
