TypeError : Argument 4 passed to PhpOffice\PhpSpreadsheet\Writer\Xlsx\Worksheet::writeAttributeIf() must be of the type string

I just updated to 1.13.0 and now when I try to save an XLS file that I just imported, I get this error:

TypeError : Argument 4 passed to PhpOffice\PhpSpreadsheet\Writer\Xlsx\Worksheet::writeAttributeIf() must be of the type string, null given, called in C:\inetpub\Intranet_Local\vendor\phpoffice\phpspreadsheet\src\PhpSpreadsheet\Writer\Xlsx\Worksheet.php on line 1164

I am not making any changes to the file, just import, then save:

$sFileImportedFromEmail      = _TEST_DATA_PATH."/imported_from_email01.xls";
$sFileImportedFromEmailSaved = _TEST_DATA_PATH."/imported_from_email_saved01.xls";

$this->expectOutputString(
	"");

try{

	$oSpreadsheet =
		IOFactory::load(
			$sFileImportedFromEmail);
	$oXlsxWriter  =
		new XlsxWriter(
			$oSpreadsheet);

	$oXlsxWriter->save(
		$sFileImportedFromEmailSaved);

}
catch(Exception $oException){

	Exceptions::convertToError(
		$oException);

	$aSpreadsheet = [];

}

Here is the file that I am importing:

Getting the exact same error while opening an xlsx template with cells having "FILL COLOR"
