When I deploy my react project into Surge, the build is successful and can get the app URL.
But when I link to the URL, I can see one blank page and some bunch of errors in the inspect console:

Failed to load resource: the server responded with a status of 404 (Not Found) 3.138a0231.chunk.css

Here is the react start script in my package.json file.

"scripts": {

  "build": "REACT_APP_BACKEND=true PUBLIC_URL='/sing-app-react' node scripts/build.js",

  "start": "node scripts/start.js",

  "start:backend": "REACT_APP_BACKEND=true node scripts/start.js",

  "test": "node scripts/test.js"

},

And the link address to css file that causes the erros https://lopsided-dinner.surge.sh/sing-app-react/static/css/3.138a0231.chunk.css
