Catchable fatal error: Argument 1 passed to Box\Spout\Common\Helper\FileSystemHelper

Hi
I wonder if you can help. I have large excel files and am trying to combine them into one. I am getting the error
Catchable fatal error: Argument 1 passed to Box\Spout\Common\Helper\FileSystemHelper::__construct() must be an instance of Box\Spout\Common\Helper\string, string given, called in /xxx/xxx/xxx/xxxx/website.com/vendor/spoutsrc/Spout/Writer/XLSX/Helper/FileSystemHelper.php on line 63 and defined in /xxx/xxx/xxx/xxxx//vendor/spoutsrc/Spout/Common/Helper/FileSystemHelper.php on line 20

replaced actual location with x's

PHP ver 7.2.33
Spout 3.2.0 I think. If you tell me how I can actually check that would be helpful

Any help appreciated

Hi !
For some reasons, the string typehint defined here:

spout/src/Spout/Common/Helper/FileSystemHelper.php

Line 20 in 9533acc

public function __construct(string $baseFolderPath)

is interpreted as belonging to the class itself. This should not be the default behavior (as you can see here: https://3v4l.org/dUDYE).
One way you can work around the issue is to add a backslash before the string (=> \string). Otherwise, I'm not sure why you are experiencing this issue...
