we-retail-journal Hello world issues

[#1]

I'm implementing the tutorial Getting Started with the AEM SPA Editor - Hello World Tutorial on AEM 6.4 (nosamplecontent) with service pack 2, when I build the app using the profile -PautoInstallSinglePackage, the build is successful and the bundles are up and active, but when I try to check the page http://localhost:4502/editor.html/content/we-retail-journal/react.html the content isn't beign rendered, checking the error.log file the unique error I'm getting is:

20.12.2018 15:02:59.069 *ERROR* [0:0:0:0:0:0:0:1 [1545336179066] GET /content/we-retail-journal/react.html HTTP/1.1] org.apache.sling.servlets.get.impl.DefaultGetServlet No renderer for extension html, cannot render resource JcrNodeResource, type=we-retail-journal/react/components/structure/app, superType=null, path=/content/we-retail-journal/react/jcr:content

Thanks for your help.

Just solved it:

• Reinstalled AEM with sample content
• Updated manually some bundles (com.fasterxml.jackson)
