When deploy your angular app on AWS amplify, the first landing page is able to load. However, when you defined a path in your router, and try to access it, you would hit Access Denied error: The solution is to navigate to AWS console, select “ Rewrites and redirects”, add a new rewrite and redirects, click on “ Open text editor”, and add the below rule:

        "source": "</^[^.]+$|\.(?!(css|gif|ico|jpg|js|png|txt|svg|woff|ttf)$)([^.]+$)/>",
        "target": "/index.html",
        "status": "200",
        "condition": null

Try again to access your url, it should work now.
