hi Kevin, yes the vapor version is usually the culprit! this course is based on our Modern Concurrency book, where [this issue was raised and fixed recently](https://forums.kodeco.com/t/swift-run-server-error/160767/27). I’ll (soon) update this course’s repo to match, but it’ll be quicker for you to download [the book’s updated materials](https://github.com/kodecocodes/mcon-materials/tree/editions/2.0).

Thanks for the heads up!
