I may have made a mistake, I upgraded to 13.1 beta and got the following error, is it possible to fix?

I’m running macOS 13 with Xcode 14.1 here and the server builds and runs for me. Can you make sure you have an up to date version of the code from GitHub - kodecocodes/mcon-materials: The projects and materials that accompany the Modern Concurrency in Swift book please?

Just in case you can try deleting first your ‘.build’ folder inside the server folder — to make sure you don’t have any old checkouts of Vapor.

Fixed, needed to blow away the repository and clone, little confusing at its still RayWenderlich on GitHub and not Kodeco.

Glad you figured it out, it’s a big migration so certainly there are still few loose ends
