Running a Blazor Server app with Amplify via Github

I tried to get my Blazor Server app running by following this tutorial: https://aws.amazon.com/de/blogs/devops/deploy-net-blazor-webassembly-application-to-aws-amplify/ However, it is for Blazor wasm and it does not seem to work for Blazor Server. I do not know why but I just get an 404 after publishing. I have also tried to use 'baseDirectory: /release' instead of 'baseDirectory: /release/wwwroot' but it did not work. Nothing useful appears on the logs, I think. It ends with:
