When I run this command it fails to integrate because there is a custom document present, but this is what created. Even after removing the custom document, there were errors with the and folders not being inside . It seems to expect the app not to use an folder even though that's the most common. Also, there's an page after calling and the homepage of the Makeswift template wasn't even visible. It just loaded forever in the builder. Once I got it all working, there were still warnings in the console.
