Hi @Imran__Khan , thanks for this.
But I've used this feature quite a few times and I think there might be a specific problem, or edge-case, with my setup which I can't debug without more insight.
I've got a fresh AEM install and generated a fresh React project with Adobe's latest Archetype 47 library, so all the code is Adobe's.
In your blog port 3) is what SHOULD happen when I run "npm run live", but instead of the AEM login page I get a 500 error and:
"[aem-site-theme-builder] Something went wrong. Proxy error:"
So the proxy server isn't responding.
