I have spent a ton of time and combed through the docs to figure out this. My custom built react component is not displaying in the editor, ever. It is showing up on the http://localhost:4502/content/wknd-events/react.model.json and in the CXR/DE. Feel like I have tried everything and I am not seeing any resources for debugging this/ a workaround. The custom-built components also do not render in ANY AEM instance but if I pull up the local build (localhost:3000) all of the items that I did add appear.
I have gone through that walkthrough and the one that uses we-journal. On the most simple leve I have just tried to build a text component from the ground up changing names slightly to just follow my trail. Using AEM 6.5.
