Describe the bug

Hello,

I'm trying to host a blazor wasm project using amplify connected to github. I followed this guide https://aws.amazon.com/fr/blogs/devops/deploy-net-blazor-webassembly-application-to-aws-amplify/ The gzip files and brotli files are well generated by the build command dotnet publish -c Release -o release but when deployed by Amplify only .js and .css are served with content-enconding to gzip.

Expected behavior

All gzip files should be served

Reproduction steps

1. Create a new blazor wasm project
2. Deploy using using amplify hosting
3. Open the web site with the network tab active

or

Open this url with network tab active: https://main.d3drcnfa1b1cqc.amplifyapp.com

Hi @emerabet try adding this SPA redirect rule via the console. Make sure to add the missing file extensions to the regex. https://docs.aws.amazon.com/amplify/latest/userguide/redirects.html#redirects-for-single-page-web-apps-spa

ex. </^[^.]+$|\.(?!(css|gif|ico|jpg|js|png|txt|svg|woff|woff2|ttf|map|json|webp|gz|br)$)([^.]+$)/>

Hi @hloriana I tried to add the rewrite rule you suggested but with no success. the browser keeps loading the .dll files instead of the .gz generated during the build

Thanks!
