Keep getting exception 'document is not defined'

[nitinsap]

Problem description

I am trying to create Windows UWP application using react-uwp.

These are the steps I follow to create react native windows app - https://microsoft.github.io/react-native-windows/docs/getting-started#running-a-react-native-windows-app

After that I am editing App.js to include Theme from react-uwp. This is my code -

`
import React, { Component } from 'react';
import {
Platform,
StyleSheet,
Text,
View
} from 'react-native';
import CheckBox from "react-uwp/CheckBox";
import { Theme as UWPThemeProvider, getTheme } from "react-uwp/Theme";
import aaa from './style.js'

const instructions =
'Press Ctrl+R to reload,\n' +
'Shift+F10 or shake for dev menu';

const theme = getTheme({
themeName: "dark",
accent: "#0078D7",
useFluentDesign: true,
userAgent: req.headers['all']
});

export default class App extends Component<{}> {
render() {
return (
<UWPThemeProvider
theme={theme}
needGenerateAcrylic={false} // if using SSR, set this config to false, using fallback color.
>

);
}
}

ReactDOM.render(
,
document.getElementById("app")
);
`

When I run this, I get exception - 'document' is not defined. Exception is coming at backdropFilterDetector.js
