TYPO3 Core

Hello,

in an environment with TYPO3 v11.5.18 and PHP 8.1 the backend module "Indexing" of EXT:indexed_search breaks in the action "List: pages" if there is an entry with multiple values (Array) like this:

The error message is "PHP Warning: Array to string conversion in /var/www/html/vendor/typo3fluid/fluid/src/Core/Parser/SyntaxTree/AbstractNode.php line 73"

To get rid of this message I've changed this line in the Fluid template from

{key}={values}

to

{key}={values -> f:format.json()}

(typo3/sysext/indexed_search/Resources/Private/Templates/Administration/Pages.html - line 64)

But I'am not sure if this is the desired solution.

Best regards!
