[522369235]

This is:

- [ ? ] a bug report
- [ × ] a feature request
- [ × ] **not** a usage question (ask them on https://stackoverflow.com/questions/tagged/phpspreadsheet or https://gitter.im/PHPOffice/PhpSpreadsheet)

What is the expected behavior?

Form(xlsx) the import

What is the current behavior?

The read XLSX table contains multiple worksheets, one of which uses an external link that does not exist, and an uncaught error occurs. (Illegal offset type)

What are the steps to reproduce?

I don't know how they made the form, but I can provide one.
The error occurs only on Linux servers.

<?php
        // use
        $spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::load($path);
        $sheetData = $spreadsheet->getActiveSheet()->toArray(null, true, true, true);

        'error_file' => '/vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Reader/Xlsx.php',
        'error_line' => 884,
        'error_msg' => 'Illegal offset type'

        // Error location code
        // Loop through contents
        foreach ($commentsFile->commentList->comment as $comment) {
              if (!empty($comment['authorId'])) {
                  $docSheet->getComment((string) $comment['ref'])->setAuthor($authors[(string)$comment['authorId']]);
              }
              $docSheet->getComment((string) $comment['ref'])->setText($this->parseRichText($comment->text));
         }
         
        // In the end
        $spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::createReaderForFile($path);
        $spreadsheet->setReadDataOnly(true);
        $sheetData = $spreadsheet->load($import['word_path'])->getActiveSheet()->toArray(null, true, true, true);

Which versions of PhpSpreadsheet and PHP are affected?

PHP: 7.4.3
phpoffice/phpspreadsheet: 1.13
