PHP Warning: Undefined array key "stdWrap2" in /data/www/sites/baden-wuerttemberg.de/shared/typo3_src/typo3_src-11.5.16/typo3/sysext/frontend/Classes/ContentObject/Menu/TextMenuContentObject.php line 123

Code:

if (($this->I['val']['stdWrap2'] ?? false) || isset($this->I['val']['stdWrap2.'])) {

If $this->I['val']['stdWrap2'] isn't set this will produce a PHP Warning.

Like this?

          if (! isset($this->I['val']['stdWrap2'])){
                $this->I['val']['stdWrap2'] = '';
            }

            if (($this->I['val']['stdWrap2'] ?? false) || isset($this->I['val']['stdWrap2.'])) {
                $stdWrap2 = (string)(isset($this->I['val']['stdWrap2.']) ? $this->WMcObj->stdWrap('|', $this->I['val']['stdWrap2.']) : '|');
                $wrapPartsStdWrap = explode($this->I['val']['stdWrap2'] ?: '|', $stdWrap2);
            } else {
                $wrapPartsStdWrap = ['', ''];
            }
