TYPO3 Undefined array key 1 - typo3

Question

I have an extbase extension. If I add a new item then I see this error:
PHP Warning: Undefined array key 1 in
/var/www/html/typo3/typo3_src-11.5.13/typo3/sysext/extbase/Classes/Routing/ExtbasePluginEnhancer.php line 202
My method:
public function listAction(): ResponseInterface
{
// List
if ($this->settings['display'] == '0') {
if ($this->settings['categories'] != '') {
if ($this->settings['important'] != '0') {
$articles = $this->getImportantFromCategories();
} else {
$articles = $this->getFromCategories();
}
} else {
if ($this->settings['important'] != '0') {
$articles = $this->getImportantArticles();
} else {
$articles = $this->getArticles();
}
}
}
// Archive
if ($this->settings['display'] == '2') {
$articles = $this->getArchivedArticles();
}
// If not details
if ($this->settings['display'] != '1') {
// Pagination
$articlesArray = $articles->toArray();
$currentPage = $this->request->hasArgument('currentPage') ? $this->request->getArgument('currentPage') : 1;
$paginator = new ArrayPaginator($articlesArray, intval($currentPage), intval($this->settings['perpage']));
$simplePagination = new SimplePagination($paginator);
$articles = $this->articleRepository->findAll();
$this->view->assignMultiple(
[
'articles' => $articles,
'paginator' => $paginator,
'pagination' =>
[
'lastPageNumber' => $simplePagination->getLastPageNumber(),
'firstPageNumber' => $simplePagination->getFirstPageNumber(),
'nextPageNumber' => $simplePagination->getNextPageNumber(),
'previousPageNumber' => $simplePagination->getPreviousPageNumber(),
'startRecordNumber' => $simplePagination->getStartRecordNumber(),
'endRecordNumber' => $simplePagination->getEndRecordNumber(),
'currentPageNumber' => $paginator->getCurrentPageNumber(),
'pages' => $simplePagination->getAllPageNumbers(),
'article_counter' => $this->article_counter,
],
'article_counter' => $this->article_counter,
]
);
}
return $this->htmlResponse();
}
and the getArticles() method:
public function getArticles()
{
$table = 'tx_extension_domain_model_article';
$query = $this->articleRepository->createQuery();
if ($this->settings['sorting'] == 'list') {
$query->statement('SELECT * FROM ' . $table . ' WHERE archived != 1');
} else {
$query->statement('SELECT * FROM ' . $table . ' WHERE archived != 1 ORDER BY crdate DESC');
}
$this->article_counter = $query->count();
return $query->execute();
}
I don't know why this error message is triggered.
The only change is the PHP Version from 7.4 to 8.0.21.
My route enhancer
routeEnhancers:
Plugin:
type: Extbase
extension: Plugin
plugin: News
routes:
- routePath: '/{slug}'
_controller: 'Article::show'
_arguments:
slug: article
- routePath: '/page/{page}'
_controller: 'Article'
_arguments:
page: currentPage
defaultController: 'Article::list'
requirements:
slug: '^[a-zA-Z0-9].*$'
page: '\d+'
aspects:
slug:
type: PersistedAliasMapper
tableName: tx_extension_domain_model_article
routeFieldName: slug
page:
type: StaticRangeMapper
start: '1'
end: '100'

Answer 1

You should look up your extbase plugin route enhancer configuration in your site configuration.
Reading the given error, and look into the corresponding code, it seems that you have a invalid value for a '_controller' or 'defaultController' configuration in there.
It should be something like MyController::myaction .. and taken the error, the second part "::myaction" seems to be missing.

Answer 2

The first error
PHP Warning: Undefined array key 1 in
/var/www/html/typo3/typo3_src-11.5.13/typo3/sysext/extbase/Classes/Routing/ExtbasePluginEnhancer.php line 202
Is solved by adding ::list in the route
- routePath: '/page/{page}'
_controller: 'Article::list'
_arguments:
page: currentPage
This will trigger
PHP Warning: Undefined array key "nonWrappedTag" in /var/www/html/typo3/typo3_src-11.5.14/typo3/sysext/frontend/Classes/ContentObject/ContentObjectRenderer.php line 3812
Solved with this TypoScript setup code
lib.parseFunc_teaser < lib.parseFunc_RTE
lib.parseFunc_teaser.nonTypoTagStdWrap.encapsLines >
lib.parseFunc_teaser.nonTypoTagStdWrap.encapsLines {
encapsTagList = p
remapTag.P =
nonWrappedTag =
}
The lines
encapsTagList = p
remapTag.P =
are not important.
