react - Refused to apply style because its MIME type ('text/html') is not a supported stylesheet MIME type

Question

After I run npm run build,

package.json

  "scripts": {
    ...
    "build": "react-scripts build"
  },

When I go to index.html, nothing inside the <div id="root"></div>.

When I open index.html

When I inspect the index.html, the console show errors

How can I solve it?
