I haven't encountered this in the wild. But I found a StackOverflow answer that links to a tweet that links to a google group...

Are you seeing this warning when you're running your app with npm start or when you're run npm build?

Thanks for the replay. That's the same page I got when I googled, but it doesn't say much. I have node and npm, but not working with it for this project.
