PHP: Need to know how to trigger onContentAfterSave on existing article

Question

I have what I thought would be a simple challenge: to automate publishing an article and trigger the onAfterContentSave event for saving the article. This code ultimately has to run within another plugin: Community Builder Auto Actions triggered by a Joomla! 4 Task Scheduler task. For now I am testing this at the command line using a verified working framework loading script.

I am not sure what I am doing wrong, but here's the code thus far. The techniques used below (middle to end of code) were obtained elsewhere online.

include ("joomla-framework.php");
use Joomla\CMS\Plugin\PluginHelper;

// (THIS WORKS) Get the oldest unpublished article whose title includes the word "test" and whose publish date is in the future.
$db = JFactory::getDbo();
$db->setQuery("SELECT id FROM `#__content` WHERE title LIKE '%test%' AND state=0 ORDER BY created ASC LIMIT 1;");
$articleId = $db->loadResult();

if ($articleId) // if there isn't one, don't do anything.
{
    //  (THIS WORKS) make sure the article is published
    $article = JTable::getInstance('content');
    $article->load($articleId);
    $article->state = 1;
    $article->store();

    $params = new stdClass();
/*
    // (THIS DOESN'T WORK) trigger the onContentAfterSave event for this article
    PluginHelper::importPlugin('content');
    $app = JFactory::getApplication();
    $app->triggerEvent('onContentAfterSave', array('com_content.article', &$article, &$params, 0));
*/

// This doesn't seem to work either, but it was my last attempt
$dispatcher = Joomla\CMS\Factory::getApplication()->getDispatcher();
$event = new Joomla\Event\Event('onContentAfterSave', array('com_content.article', &$article, &$params, 0));
$res = $dispatcher->dispatch('onContentAfterSave', $event);

The idea here is to trigger onContentAfterSave on the identified article, which has a custom field (flag) telling one of my plugins to send an email containing the article. That plugin works perfectly when saving a published article in either the site front or back end, but I need to be able to trigger it from a Task Scheduler cronjob.

Any assistance would be truly appreciated. Thanks in advance!

P.S. No errors are occurring with either of the two above triggering methods.

Edit: Looking around a bit more, I think that first method was along the right line. Here's what I think that last part should look like. Note that this doesn't trigger the event either.

// trigger the onContentAfterSave event for this article (THIS DOESN'T WORK)
Factory::getApplication()->triggerEvent('onContentAfterSave', ['com_content.article', &$article, false, array()]);

Assuming you're using CliApplication it's maybe the case that it doesn't get everything it needs out of the Dependency Injection container. (I know that it doesn't get the JConfig params for example).

I suggest you try the following. Instead of

$app = Factory::getApplication();

try doing:

$dic = Factory::getContainer();
$app = $dic->get('Joomla\CMS\Application\ConsoleApplication');

For a proper solution you'd be best to go down the route of writing a Joomla 4 CLI Application though.

Update -------------------------------------

The other thing you could try would be to enclose your code after including your joomla-framework.php within a class which extends Joomla\CMS\Application\CliApplication:

use Joomla\CMS\Application\CliApplication;

class Testapp extends CliApplication
{
    public function doExecute()
    {
        Factory::$application = $this;  // you probably need this
        $dic = Factory::getContainer();
        $app = $dic->get('Joomla\CMS\Application\ConsoleApplication');
        Factory::$application = $app;  // you might need this too
        //etc
    }

    public function getName()   // you need to specify this function
    {
        return "test";  // doesn't matter what you set
    }
}

CliApplication::getInstance('Testapp')->execute();
