Answer 1

Add this to your config:

{
  "settings": {
    "react": {
      "version": "detect"
    }
  }
}

See the config here: https://github.com/jsx-eslint/eslint-plugin-react/blob/master/README.md#configuration

Answer 2

The problem is in the eslint-plugin-react v.7.30.1. Downgrade it to v.7.30.0 and it will work

"eslint-plugin-react": "^7.30.0"
