[Solved] How to remove, delete the cache file for just one resource?

$resFive = $modx->getObject('modResource',5);
$cacheKey = $resFive->getCacheKey();
$modx->cacheManager->delete($cacheKey);

$resFive = $modx->getObject('modResource',5);
 $modx->cacheManager->refresh(array(
	'db' => array(),
	'auto_publish' => array('contexts' => array($resFive->get('context_key'))),
	'context_settings' => array('contexts' => array($resFive->get('context_key'))),
	'resource' => array('contexts' => array($resFive->get('context_key'))),
));

$resFive = $modx->getObject('modResource',5);
$cacheKey = $resFive->getCacheKey();
$file = $path_to_cache.$cacheKey.'.cache.php'; //Something like: 'cache/resource/web/resources/5.cache.php
unlink($file);

$modx->getCacheManager();  // harmless and sometimes necessary
$modx->cacheManager->delete('resource/web/resources/5.cache.php');

<?php
// This bit works fine:
$cm = $modx->getCacheManager();
$resource = $modx->getObject('modResource',1);
$results = $cm->generateResourceHack($resource);

// This bit does not work:
$cm->delete('resource/web/resources/5.cache.php');

<?php
/* get the cache provider for the "resource" cache partition */
$resourceCache = $modx->cacheManager->getCacheProvider($modx->getOption('cache_resource_key', null, 'resource'));

$resFive = $modx->getObject('modResource', 5);
$resourceCache->delete($resFive->getCacheKey());

<?php
$modx->setLogLevel(modX::LOG_LEVEL_DEBUG);
$modx->log(modX::LOG_LEVEL_DEBUG, '############test create cache file');
