I downloaded the magnolia-community-demo-webapp with tomcat from this link https://docs.magnolia-cms.com/product-docs/6.2/Developing/Bundles-and-webapps.html and found the public instance folder almost empty.
I then downloaded the magnolia-community-demo-webapp WAR from the same link and deployed it. It works but when I click the publishing module to get the code to be used in the author it generates a null pointer exception error.

How can I run a public instance to publish content from the author?
