ErrorException Undefined array key 38

Description:

I'm getting an error when trying to run getDataTm() on a pdf. I have tried this on a native LAMP stack and inside a Symfony 6.3.6 framework.
ErrorException - Undefined array key 38

PDF input

420399_20231024.pdf

Expected output & actual output

Code

    $parser = new Parser();
    $pdf = $parser->parseFile($uploadedFile);
    $totalPages = $pdf->getDetails()['Pages'];
    for ($p = 0; $p < $totalPages; $p++) {
          **$data[$p] = $pdf->getPages()[$p]->getDataTm();   //  <---- error happen here**
    }

I temporary solved wrapping the read of array "$extractedTexts" in a "array_key_exists()" checking and all pdf texts seems correctly retrivied except for last text in the bottom right:"Page 1 of n" that is lost.

In "vendor/smalot/pdfparser/src/Smalot/PdfParser/Page.php":

Before fix:

704	$currentText = $extractedTexts[\count($extractedData)];
705         switch ($command['o']) {

After fix:

704     if (array_key_exists(\count($extractedData), $extractedTexts)) {
705         $currentText = $extractedTexts[\count($extractedData)];
706         switch ($command['o']) {
              . . .
878         }
879	}

Start in src/Smalot/PdfParser/Page.php around line 704, then reproduce getDataTm() with the attached PDF and the reported PHP 8.1 setup. Trace how extractedTexts and extractedData are indexed during parsing. Done means the PDF parses without an undefined array key and the bottom-right “Page 1 of n” text is not lost.
