How can I fix the following deprecation error generated by my php code?

Factory::getDocument() is deprecated

$app = Factory::getApplication();
$wa = $app->getDocument()->getWebAssetManager();

if (!$wa->assetExists('script', 'keyselectmodal'))
    $document = Factory::getDocument();

Use Joomla\CMS\Application\WebApplication::getDocument(). In your code you're already doing this with $app->getDocument().

  • In your code you only need to replace Factory::getDocument() with $app->getDocument().
