Ares launch for ReactJS build folder did not work

I have create a new App for LG tv with ReactJS. After build app with “npm run build”, I had build folder with index.html and static asset (css, js, media).
I create a sample app with “ares-generate” and put my build folder in it and run “ares-launch”, but there is nothing appear in my app. It seems like my static asset can not load.
Can any one help me to fix this issue, I really appreciate that

Does your app work on a general web browser? The index.html is the first page of your app, and the path to each asset should be specified relative to the index.html file. You can find more information in App Resources. Thank you.
