React Router DOM not working correctly on Amplify Console AWS

I have deployed react app on Amplify Console following their documentation. The site is deployed and running fine, I am able to navigate using links but when I try to land to any url directly I get redirected to my configured 404 page.

Below is the code I am using

ReactDOM.render(
  <Router>
    <Route path="/" component={App} />
  </Router>,
  document.getElementById("root"),
);

And here is how my route looks like -

<Switch>
    <Route
      exact
      path="/"
      render={(): JSX.Element => <Home auth={this.auth} />}
    />
    <Route path="/features" render={(): JSX.Element => <Features />} />
    <Route
      path="/pagenotfound"
      render={(): JSX.Element => <PageNotFound />}
    />
    <Redirect from="/**" to="/pagenotfound" />
</Switch>

Here is the link to the app - https://master.dkf0zemoh330o.amplifyapp.com/features

This happens because navigating directly to a path or reloading a path requests that path on the server, but React Router can only control routes on the client.

I was able to work around that limitation with Amplify using redirect settings, as mentioned in these two GitHub issues:

From the Amplify console, you can access the Rewrites and redirects menu item in left sidebar. From there you can update the redirect rule to these settings:

Source address: </^[^.]+$|\.(?!(css|gif|ico|jpg|js|png|txt|svg|woff|ttf)$)([^.]+$)/>
Target address: /index.html
Type: 200

This uses their regex source feature that matches problematic routes and redirects them to index.html. You may need to replace this default route with / or something else depending on how your app is structured. Here's what it should look like:

If the steps above don't fully work try adding <base href="/" /> to the <head/> section of your index.html as mentioned here, sadly this took a while to find.

For a complete answer this is my final "Rewrites and redirects" opened in the text editor:

[
    {
        "source": "https://example.com",
        "target": "https://www.example.com",
        "status": "302",
        "condition": null
    },
    {
        "source": "</^[^.]+$|\\.(?!(css|gif|ico|jpg|js|png|txt|svg|woff|woff2|ttf|map|json|webp|html|xml|webmanifest|mp4)$)([^.]+$)/>",
        "target": "/index.html",
        "status": "200",
        "condition": null
    },
    {
        "source": "/<*>",
        "target": "/index.html",
        "status": "404-200",
        "condition": null
    }
]

Thanks! I would add also |json| the string - it fixes "Manifest: Line: 1, column: 1, Syntax error on Chrome browser" problem:

Manifest: Line: 1, column: 1, Syntax error on Chrome browser
