Error when $oMerger->duplexMerge();

[flymke]

I get an error when trying to use $oMerger->duplexMerge();

Cannot access protected property setasign\Fpdi\Fpdi::$page

/webklex/laravel-pdfmerger/src/PDFMerger/PDFMerger.php on line 250

Any hints on that?

Does anyone know if there is any progress on this issue?
I can change the line 250 of PDFMerger.php to:
$oFPDI->PageNo() % 2
But I thought that in version 1.3.2 it would be solved...
