Uncaught Error: Call to a member function attributes() on null about phpspreadsheet

[arnaudelub]

Hi there, thanks for your answer, i'm using this code for hundreds of xls / xlsx / csv files and it works well except for some of them:

$reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReaderForFile($file);
$reader->setReadDataOnly(true);
$objReader=$reader->load($file);
$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($objReader, "CSV");
$writer->save("test.csv");

The XMLThemeName object appears to be empty, so there is no $xmlTheme->themeElements->clrScheme->attributes();

I can't give you the xlsx file here but here is the theme.xml
phpSpreadsheet_error_theme.txt

Thanks for your help!

The description seems to lack important information to do anything about it. Closing for now, but feel free to add a fully reproducible example of code that reproduce the issue and reopen it.

@BadTasTe- are you sure, you use a CSV file with this? Because The failing class in Xlsx which hints that your file is maybe an XLSX (new M$ Office format) or your code is something nasty.

Please provide a code as @PowerKiKi asked for.

I am facing the same issue with couple of xlsx file. Unfortunately, we are not at the liberty to share the files to be able to reproduce in-house for you.
