Are you asking for these settings?
It is loading outside of the rig. I run npm start on the front and backends and it starts right up with no issues. Not sure what you mean by “the folder React outputs to?”. Are you talking about the folder I start the app from?
It for sure could be a React issue. But from looking around I can’t really find anyone who has ran into this issue.
Are you sure it doesn’t have anything to do with the manifest.json? Am I supposed to have that file in my extension folder?
