Errors with Igor RC2 and PHP Version 8.1.6

[saggi-dw]

On a test installation of Igor with xampp and PHP 8.1 I get the following errors:

Warning: Undefined array key "lang" in E:\xampp\htdocs\dokuwiki\lib\plugins\wrap\helper.php on line 94
Warning: Undefined array key "id" in E:\xampp\htdocs\dokuwiki\lib\plugins\wrap\helper.php on line 117
Warning: Undefined array key "dir" in E:\xampp\htdocs\dokuwiki\lib\plugins\wrap\helper.php on line 128

with the expression

<WRAP center round info 60%>
info box
</WRAP>

Also with others, like columns I get Undefined array key warnings. If more information is needed I can provide it.
