First remove the &includeContent=`1` and see if the snippet returns an array. If you don’t get an array then you have an issue with the snippet and you will have to look at your settings.
If an array is returned then create a template chunk like you would with ditto.
[[getResources? &parents=`1` &tpl=`myTpl`]]
Here is an example of a simple chunk
<h2>[[+pagetitle]]</h2>
<p>
[[+introtext]] - <a class="readmore" href="[[~[[+id]]]]" title="[[+pagetitle]]">read more ..</a>
</p></p>
Read the comments in the snippet for more info and look at the return on the array for your placeholders.
Re: the link in the chunk.. Links in Revo are [[~id]] and the placeholder from getResources is [[+id]] so wrap it as shown in the code example above.
The snippet is working for me.
