I think we need to add the property under /content/your-folder/jcr:content as**: jcr:title : give the exact name . Click on add and save all.

We found missing jcr:content nodes for some pages under /content. Some existing jcr:content nodes were missing jcr:title property. We added the missing jcr:content nodes and jcr:title property. This solved the issue.

Note: The root of any of the sites (specifically sub-sites) should contain the following within their jcr:content – 1. Title 2. cq:allowedTemplates - to define the templates that go with this site specifically. 3. designPath – which defines the clientlibs for the site and can contain options for the sidekick.

Go to crx-quickstart folder in your file system and search for pagecard_jsp.java.

What is on line 99? I have a different version but I guess it is this line:

Resource commentsResource = page.getContentResource().getChild("alt/comments");

If this line throws a NPE, it means that one of the top-level pages under /content is missing jcr:content node or the node is corrupted.

It is just a wild guessing without details.
