TYPO3 Core

When setting special.value to a non-existing UID or a hidden page the HMENU "browse" produces one of those PHP 8 warnings:

PHP Warning: Undefined array key "pid" in EXT:frontend/Classes/ContentObject/Menu/AbstractMenuContentObject.php line 988

974  protected function prepareMenuItemsForBrowseMenu($specialValue, $sortingField, $additionalWhere)
...
988     if ($value_rec['pid']) {
989        // The page record of 'up'.
990        $recArr['up'] = $this->sys_page->getPage((int)$value_rec['pid'], $this->disableGroupAccessCheck);
991     }

Example TypoScript:

page.10 = HMENU
page.10 {
  special = browse
  special.items = next
  special.value = 1234567890
  1 = TMENU
  1.NO {
    wrap = |
  }
}
